     DETAILED DESCRIPTION 
     Referring to the drawings and in particular to  FIG. 1 , an exemplary embodiment of a guard assembly according to the present disclosure is shown and is generally referred to by reference numeral  10 . Guard assembly  10  is installed on a deadend of a power line assembly  100 . Power line assembly  100  has a conductor  101  that is connected to a deadend clamp  102  that are both energized. Deadend clamp  102  is, for example, a bolted shoe, as shown in  FIG. 1 , or wedge. Deadend clamp  102  connects conductor  101  to an insulator  104  that has sheds  106 . Guard assembly  10  has a first guard cover portion  12 , second guard cover portion  14  and a clamp  200 . Alternatively, clamp  200  can be used without first guard cover portion  12  and second guard cover portion  14 . Another alternative includes first guard cover portion  12  and second guard cover portion  14  that can be a single piece. For example, first guard cover portion  12  and second guard cover portion  14  are not two separate halves but one large guard (totaling the two halves). Although a single guard body that combines first guard cover portion  12  and second guard cover portion  14  is a sound option to provide protection, it can have limitations. A conductor such as conductor  101  exiting a deadend clamp, for example, deadend clamp  102 , downward can use either a solid one-piece or a two-piece guard. However, a conductor, such as conductor  101 , exiting the deadend clamp, for example, deadend clamp  102 , upward can only make use of a two-piece guard, for example, first guard cover portion  12  and second guard cover portion  14 . Referring to  FIG. 12 , first guard cover portion  12  has first loops  43  and second guard cover portion  14  has second loops  45  that are each hot stick loops allowing for hanging above equipment, for example, power line assembly  100 , to locate as well as another attachment point to push down into the equipment if necessary/advantageous. 
     Advantageously, guard assembly  10  has clamp  200  that mounts directly to insulator  104  of a deadend of power line assembly  100 . The end user will be required to vertically orient clamp  200  relative to the ground below regardless of the deadend of power line&#39;s  100  existing position. Clamp  200  ensures correct placement of first guard cover portion  12  and second guard cover portion  14  as well as providing them with a positive retention to clamp  200  itself. 
     Referring to  FIG. 2 , guard assembly  10  has first guard cover portion  12 , second guard cover portion  14  and clamp  200 . First guard cover portion  12  is shaped to cover a portion of the deadend of power line assembly  100 . First guard cover portion  12  has a first side opening  16 , a first middle opening  18  and a first open bottom  21 . Second guard cover portion  14  is shaped to cover another portion of the deadend of power line assembly  100 . Second guard cover portion  14  has a second side opening  22 , a second middle opening  24  and a second open bottom  26 . First guard cover portion  12  and second guard cover portion  14  are made of a material, for example, a thermoplastic compound. 
     Clamp  200  has a fixed jaw  202 , a moveable jaw  204 , a bolt  206  and two jaw faces  208 . Fixed jaw  202  is made of a material, for example, a thermoplastic compound. Moveable jaw  204  is made of a material, for example, a thermoplastic compound. Bolt  206  is made of a material, for example, a thermoplastic compound.

Top member  210  has a depression  211  shaped to receive jaw face  208 . Bottom member  212  has a slot  216  forming edge walls  215 ,  217  ( FIG. 9 ). 
     Referring to  FIG. 4 , moveable jaw  204  has a jaw body  218 . Jaw body  218  has a depression  220  having a protruded side  222  and receiving side  224 . Protruded side  222  is shaped to receive jaw face  208 . Receiving side  224  has opening  226  so that bolt  206  can pass through moveable jaw  204 . Receiving side  224  can be threaded in opening  226 . Receiving side  224  has grooves  225 ,  227  forming a slider  229 . 
     Referring to  FIG. 5 , jaw face  208  has a face body  228 . Face body  228  has a mating portion  230  that is shaped to be received in depression  211  of fixed jaw  202  or depression  220  of moveable jaw  204 . Jaw face  208  has an insulator receiving side  232  that is opposite mating portion  230  that is shaped to clamp insulator  104 . Jaw faces  208  can be removable from fixed jaw  202  and moveable jaw  204  and replaced with other jaw faces having different diameters or materials to provide greater or less friction. Jaw faces  208  can have rubberized teeth to assist with gripping insulator  104 . 
     Referring to  FIG. 6 , bolt  206  has a bolt body  234 . Bolt body  234  has a mating portion  236 . Mating portion  236  can have threads  235  as shown in  FIG. 9 . Bolt body  234  has a stop ridge  238 . Bolt body  234  has a loop ridge  240  and loop  242 . 
     Referring to  FIGS. 7-10 , clamp  200  has two of jaw faces  208 . One of jaw faces  208  is connected to moveable jaw  204  in depression  220 , for example, by snap fit. The other of jaw faces  208  is connected in depression  211  of fixed jaw  202 , for example, by snap fit. Referring to  FIG. 9 , edge walls  215 ,  217  of fixed jaw  202  each fit into one of grooves  225 ,  227  of moveable jaw  204  so that slider  229  extends out of slot  216  on a side of edge walls  215 ,  217  opposite a side facing jaw faces  208 . Slider  229  is sized larger than slot  216  to maintain moveable jaw  204  in slot  216 . Mating portion  236  of bolt  206  passes through opening  214  of fixed jaw  202  and through opening  226  of moveable jaw  204 . Threads in opening  214  of fixed jaw  202  mate with threads  235  of mating portion  236  of bolt  206 . Threads in opening  226  of moveable jaw  204  mate with threads  235  of mating portion  236  of bolt  206 . Moveable jaw  204  rests on stop ridge  238 . 
     In operation, when bolt  206  is rotated in a first direction, bolt  206  moves in a direction A, shown in  FIG. 8 , so that ridge  238  of bolt  206  moves moveable jaw  204  in direction A to move protruded side  222  of moveable jaw  204  closer to top member  210  of fixed jaw  202  moving two jaw faces  208  closer together. When bolt  206  is rotated in a second direction opposite to the first direction, bolt  206  moves in a direction B, shown in  FIG. 9 , so that ridge  238  of bolt  206  moves moveable jaw  204  in direction B to move protruded side  222  of moveable jaw  204  away from top member  210  of fixed jaw  202  moving two jaw faces  208  further a part. Slider  229  moves in slot  216  in both the direction A and the direction B when bolt  206  is rotated in either the first direction or the second direction to maintain a connection and alignment between fixed jaw  202  and moveable jaw  204 . 
     Referring to  FIG. 12 , to install guard assembly  10 , a lineman can use a hot stick with guard assembly  10 . Clamp  200  attaches to insulator  104  and clamp  200  is pivoted to ensure it is tightened in a vertical orientation relative to the ground below despite the equipment position of powerline  100 . Clamp  200  is tightened in the vertical orientation on insulator  104  by positioning clamp  200  between a first shed  106   a  and deadend clamp  102  and placing fixed jaw  202  and moveable jaw  204  around insulator  104  so that bolt  206  is then rotated in the first direction to move bolt  206  in the direction A, shown in  FIG. 8 , and ridge  238  of bolt  206  moves moveable jaw  204  in direction A to move protruded side  222  of moveable jaw  204  closer to top member  210  of fixed jaw  202  moving two jaw faces  208  closer together connecting clamp  200  to insulator  104 . Slider  229  moves in slot  216  in the direction A when bolt  206  is rotated the first direction to maintain the connection and alignment between fixed jaw  202  and moveable jaw  204 . The hot stick can be inserted into loop  242  to allow for rotation. Referring to  FIG. 14 , first guard cover portion  12  is then installed overlapping first shed  106   a  of insulator  104 . Alternatively, first guard cover portion  12  may cover a portion of insulator  104  that does not include first shed  106   a . First guard cover portion  12  has four clip portions  20  so that two of four clip portions  20  can be positioned on each side of clamp  200  to clip first guard cover portion  12  onto clamp  200  by snap fit. First guard cover portion  12  is pressed downward in direction B so that each of clip portions  20  that have a slanted surface contacts clamp  200  to move opposite sides  30 ,  32  of first guard cover portion  12  away from one another deforming first guard cover portion  12  outward over clamp  200  until each of clip portions  20  is below clamp  200  allowing opposite sides of first guard cover portion  12  to move closer together positioning clip portions  20  under clamp  200  to connect first guard cover portion  12  to clamp  200 . Once first guard cover portion  12  and clamp  200  are connected, there can be space between clip portions  20  and moveable jaw  204  to allow for limited movement therebetween. Referring to  FIGS. 14 and 15 , first guard cover portion  12  has an alignment projection  28 . Alignment projection  28  has a middle surface  34  and slanted surfaces  36 ,  38  on opposite sides of middle surface  34 . Alignment projection  28  has slanted surfaces  36 ,  38  that limit horizontal movement of clamp  200  during connection of first guard cover portion  12  to clamp  200  to assist with placement of first guard cover portion  12  on clamp  200  during installation. A space can be formed between middle surface of alignment projection  28  and a portion of bolt  206  that extends out of fixed jaw  202  to allow for movement of bolt  206  relative to fixed jaw  202  to move moveable jaw  204 . Second guard cover portion  14  then overlaps and clips by snap fit into first guard cover portion  12 . Alternatively, there can be different versions of second guard cover portion  14  which will overlap and clip by snap fit into first guard cover portion  12  depending on a configuration of power line assembly  100 . 
     Referring to  FIG. 11 , guard assembly  10  can accommodate a modified power line assembly  100   a  that is a wedge assembly. Referring to  FIG. 13 , guard assembly  10  can accommodate a modified power line assembly  100   b  that is another wedge assembly. 
     Guard assembly  10  is now a 3-component assembly that accommodates a wide range of equipment while ensuring proper coverage. Clamp  200  attaches to insulator  104  just before deadend clamp  102  or other deadend clamp, shoe or wedge assembly. Guard assembly  10  has a user friendly installation and removal that mimics existing work methods of a typical hot line clamp. Clamp  200  features jaw faces  208  that allow for various diameters of insulators  104  while providing a secure grip. 
     Clamp  200  mimics the action of a typical hot line clamp. Clamp  200  is a vise clamp style device of a polymer makeup that will clamp to the end of a deadend insulator  104  just before deadend clamp  102 . This allows for the end user to tighten clamp  200  in a vertical orientation ensuring proper guard coverage. Guard assembly  10  will mount overtop of clamp  200  snapping into place via internal snap hooks on first guard cover portion  12 . This design came about after realizing too many variables existed with deadend clamps, for example, shoes and wedges, to create a universal guard. The most consistent element was insulator  104 , but it did not provide a solid feature to ensure vertical orientation (due to cylindrical profile). Guard assembly  10  having clamp  200  provides ensures this vertical orientation. 
     Referring to  FIGS. 16 and 17 , clamp  200  can be modified to clamp  1600 . Clamp  1600  is the same as clamp  200  except clamp  1600  includes torque bolt  1606  instead of bolt  206 , and, accordingly, the features that are the same for clamp  200  and clamp  1600  use the same reference numerals. Referring to  FIG. 18 , torque bolt  1606  has a bolt body  1634 . Bolt body  1634  has a mating portion  1636 . Mating portion  1636  can have threads  1635 . Bolt body  1634  has a stop ridge  1638 . Bolt body  1634  has a loop ridge  1640  and loop  1642 . A hex head  1644  is below loop ridge  1640 . A necked down area  1646  is just above loop  1642  and below hex head  1644 . Torque bolt  1606  is made of a material, for example, a thermoplastic compound, aluminum, aluminum alloy and any combination thereof. 
     Mating portion  1636  of bolt  1606  passes through opening  214  of fixed jaw  202  and through opening  226  of moveable jaw  204 . Threads in opening  214  of fixed jaw  202  mate with threads  1635  of mating portion  1636  of bolt  1606 . Threads in opening  226  of moveable jaw  204  mate with threads  1635  of mating portion  1636  of bolt  206 . Moveable jaw  204  rests on stop ridge  1638 . 
     Referring to  FIGS. 18 and 19 , during operation, to install clamp  1600 , a lineman can use a hot stick  1900 . Clamp  1600  attaches to insulator  104  and clamp  1600  is pivoted to ensure it is tightened in a vertical orientation relative to the ground below despite the equipment position of powerline  100 . Clamp  1600  is tightened in the vertical orientation on insulator  104  by positioning clamp  1600  between first shed  106   a  and deadend clamp  102  and placing fixed jaw  202  and moveable jaw  204  around insulator  104  so that torque bolt  1606  is then rotated in the first direction to move bolt  1606  in the direction A, shown in  FIG. 18 , and ridge  1638  of bolt  1606  moves moveable jaw  204  in direction A to move protruded side  222  of moveable jaw  204  closer to top member  210  of fixed jaw  202  moving two jaw faces  208  closer together connecting clamp  1600  to insulator  104 . Slider  229  moves in slot  216  in the direction A when bolt  206  is rotated the first direction to maintain the connection and alignment between fixed jaw  202  and moveable jaw  204 . The hot stick can be inserted into loop  1642  to allow for rotation. Once a predetermined amount of tension is applied to clamp  1600 , then torque bolt  1606  breaks along necked down area  1646  so that loop  1642  is disconnected from hex head  1644 . This will ensure adequate tension is applied to the overall clamp as well as eliminate risk of overtightening. Hex head  1644  is included as backup to allow for clamp  1600  to be removed once loop  1642  has been sheared off by rotating hex head  1644  to move torque bolt  1606  in the second direction opposite to the first direction, to move bolt  1606  in direction B, shown in  FIG. 18 , so that ridge  1638  of bolt  1606  moves moveable jaw  204  in direction B to move protruded side  222  of moveable jaw  204  away from top member  210  of fixed jaw  202  moving two jaw faces  208  further a part. Clamp  1600  connects to first guard cover portion  12  in the same way as clamp  200  connects to first guard cover portion  12 . Second guard cover portion  14  can then be connected to first guard cover portion  12  as described herein. Similar to clamp  200 , clamp  1600  can be used without first guard cover portion  12  and second guard cover portion  14  or first guard cover portion  12  and second guard cover portion  14  that can be a single piece. 
     Two jaw faces  208  can be a material that has a 80 shore A hardness. Fixed jaw  202  and moveable jaw  204  can be made of, for example, glass filled acetal or glass filled polybutylene terephthalate. 
     Clamp  1600  that includes torque bolt  1606  thus provides adequate tension to be applied to the overall clamp  1600  as well as eliminates risk of overtightening. Hex head  1644  also provides a backup to allow for clamp  1600  to be removed once loop  1642  has been sheared off. 
       FIGS. 20-23  depict an example captive shear bolt assembly  100 ′ that can be used with clamp  1600  instead of torque bolt  1606  in a modified clamp  1600 . Accordingly, the modified clamp  1600  is the same as clamp  1600  that is not modified except uses captive shear bolt assembly  100 ′ instead of torque bolt  1606 . Captive shear bolt assembly  100 ′ is the same as captive shear bolt assembly 100 of U.S. patent application Ser. No. 16/582,532 filed Sep. 25, 2019 that is hereby incorporated by reference except captive shear bolt assembly  100 ′ adds a stop ridge  138 ′ for moveable jaw  204  to rest on. Stop ridge  138 ′ is the same as stop ridge  1638  of torque bolt  1606 . 
     The example captive shear bolt assembly  100 ′ may include a bolt  110 ′, a cap nut  120 ′, and a screw  130 ′. The bolt  110 ′ may include a head  112 ′, a shank  114 ′, and a stud  115 ′. The head  112 ′ may be hexagonal. The head  112 ′ may define a top surface  122 ′ and a bottom surface  123 ′. The stud  115 ′ may extend from the top surface  122 ′. The shank  114 ′ may extend from the bottom surface  123 ′. The shank  114 ′ may include a shoulder  116 ′, a threaded portion  118 ′, a non-threaded portion  124 ′, and a protrusion  128 ′. The shoulder  116 ′ may be between the bottom surface  123 ′ of the head  112 ′ and the threaded portion  118 ′. The threaded portion  118 ′ may be between the shoulder  116 ′ and the non-threaded portion  124 ′. The non-threaded portion  124 ′ may have a first cross-sectional area that is less than or equal to a minor diameter of the threaded portion  118 ′. The protrusion  128 ′ may define the distal end  126 ′ of the shank  114 ′. The protrusion  128 ′ may have a second cross sectional area that is less than the first cross sectional area of the threaded portion  118 ′. The protrusion  128 ′ may be configured to accept a lock washer or a retaining ring. For example, a retaining ring may be radially or axially installed onto the protrusion  128 ′. 
     The bolt  110 ′ may define a cavity  140 ′. The cavity  140 ′ may be located (e.g., centered) at an axis of rotation  160 ′ of the bolt  110 ′. The cavity  140 ′ may extend through the stud  115 ′ and the head  112 ′. The cavity  140 ′ may extend partially into the shank  114 ′. The cavity  140 ′ may be configured to receive the screw  130 ′. For example, the cavity  140 ′ may include internal threads  146 ′. The internal threads  146 ′ of the cavity  140 ′ may begin after the shear section  142 ′. 
     The stud  115 ′ may be threaded. For example, the stud  115 ′ may include external threads  144 ′. The stud  115 ′ may define a shear section  142 ′. The shear section  142 ′ may be between the top surface  122 ′ of the head  112 ′ and the external threads  144 ′. The shear section  142 ′ may define a tapered cross section with a first diameter at the top surface  122 ′ of the head  112 ′ and a second diameter at a start of the external threads  144 ′. The first diameter may be greater than the second diameter. The shear section  142 ′ may be configured to shear at or above a threshold torque. For example, the second diameter may be determined based on the threshold torque. 
     The cap nut  120 ′ may be hexagonal (e.g., a hexagonal cap nut). The cap nut  120 ′ may define an orifice  150 ′ on the top surface  152 ′ of the cap nut  120 ′. The orifice  150 ′ may be configured to receive the screw  130 ′. For example, the orifice may receive one or more threads  132 ′ of the screw  130 ′ and/or a head  134 ′ of the screw  130 ′. The cap nut  120 ′ may include internal threads that allow the cap nut  120 ′ to be threaded onto the stud  115 ′. When the cap nut  120 ′ is threaded onto the stud  115 ′, the orifice  150 ′ may be aligned with the cavity  140 ′ such that the screw  130 ′ may be installed in the cavity  140 ′ through the orifice  150 ′. 
     The screw  130 ′ may include threads  132 ′ and a head  134 ′. The head  134 ′ may define a recessed drive hole  136 ′. The recessed drive hole  136 ′ may be configured to receive a hexagonal (e.g., such as an Allen wrench) drive. 
     The cap nut  120 ′ may be threaded onto the bolt  110 ′. For example, the cap nut  120 ′ may be threaded onto the external threads  144 ′ of the stud  115 ′. The screw  130 ′ may be inserted into the cavity  140 ′ via the orifice  150 ′. The captive shear bolt assembly  100 ′ may be configured to be driven at the cap nut  120 ′. As torque is applied to the cap nut  120 ′, the captive shear bolt assembly  100 ′ may rotate as the threaded portion  118 ′ engages complementary threads, namely, threads in opening  214  of fixed jaw  202  and threads in opening  226  of moveable jaw  204  so that when fixed jaw  202  and moveable jaw  204  are placed around insulator  104 , captive shear bolt assembly  100 ′is then rotated in the first direction to move captive shear bolt assembly  100 ′ in the direction A, shown in  FIG. 18 , and stop ridge  138 ′ of captive shear bolt assembly  100 ′ moves moveable jaw  204  in direction A to move protruded side  222  of moveable jaw  204  closer to top member  210  of fixed jaw  202  moving two jaw faces  208  closer together connecting the modified clamp  1600  to insulator  104 . When the applied torque exceeds a threshold torque, the shear section  142 ′ of the stud  115 ′ may shear such that the cap nut  120 ′ and the stud  115 ′ are mechanically decoupled from the threaded portion  118 ′ of the bolt. For example, when the shear section  142 ′ shears, the cap nut  120 ′ may no longer drive the threaded portion  118 ′ of the bolt  110 ′. When the shear section  142 ′ of the stud  115 ′ shears, the screw  130 ′ may captively secure the cap nut  120 ′ and the stud  115 ′ to the bolt  110 ′. For example, the screw  130 ′ may engage threads in the head  112 ′ portion of the cavity  140 ′. Similar to torque bolt  1606 , once a predetermined amount of tension is applied to the modified clamp  1600 , then captive shear bolt assembly  100 ′ breaks along shear section  142 ′. This will ensure adequate tension is applied to the overall clamp  1600  as well as eliminate risk of overtightening. 
       FIGS. 24-26  depict another example of a captive shear bolt assembly  300  that can be used with clamp  1600  instead of torque bolt  1606  in a modified clamp  1600 . Accordingly, the modified clamp  1600  is the same as clamp  1600  that is not modified except uses captive shear bolt assembly  300  instead of torque bolt  1606 . Captive shear bolt assembly  300  is the same as captive shear bolt assembly 300 of U.S. patent application Ser. No. 16/582,532 filed Sep. 25, 2019 that is hereby incorporated by reference except captive shear bolt assembly  300  adds a stop ridge  338  for moveable jaw  204  to rest on. Stop ridge  338  is the same as stop ridge  1638  of torque bolt  1606 . 
     The example captive shear bolt assembly  300  may include a bolt  310 , a shear coupling  315 , and a screw  330 . The bolt  310  may include a head  312  and a shank  314 . The head  312  may be hexagonal. The head  312  may define a top surface  322  and a bottom surface  323 . The shank  314  may extend from the bottom surface  323 . The shank  314  may include a shoulder  316 , a threaded portion  318 , a non-threaded portion  324 , and a protrusion  328 . The shoulder  316  may be between the bottom surface  323  of the head  312  and the threaded portion  318 . The threaded portion  318  may be between the shoulder  316  and the non-threaded portion  324 . The non-threaded portion  324  may have a first cross-sectional area that is less than or equal to a minor diameter of the threaded portion  318 . The protrusion  328  may define the distal end  326  of the shank  314 . The protrusion  328  may have a second cross sectional area that is less than the first cross sectional area of the threaded portion  318 . The protrusion  328  may be tapered from the shank  314  to the distal end  326 . The protrusion  328  may be configured to accept a retainer (e.g., such as a retaining ring and/or a lock washer). 
     The shear coupling  315  may define an upper head  320 , a lower head  325 , and a shear section  342 . The upper head  320  and/or the lower head  325  may be hexagonal-shaped. For example, the upper head  320  may be a first hexagonal nut and the lower head  325  may be a second hexagonal nut. The upper head  320  and the lower head  325  may be connected by the shear section  342 . The upper head  320  may be configured to receive an external torque. The shear section  342  may define a tapered cross section with a first diameter at the upper head  320  and a second diameter at the lower head  325 . The first diameter may be greater than the second diameter. The shear section  342  may be configured to shear at or above a threshold torque. For example, one or more of the second diameter, the material, and/or the thickness of the shear section  342  may be determined based on the threshold torque. 
     The shear coupling  315  may define an orifice  350 . The orifice  350  may extend through the upper head  320 , the shear section  342 , and the lower head  325 . For example, the orifice  350  may start at a top surface  352  of the upper head  320  and may terminate at a bottom surface  354  of the lower head  325 . The orifice  350  may be configured to receive the screw  330 . For example, the orifice may receive one or more threads  332  of the screw  330  and/or a head  334  of the screw  330 . 
     The bolt  310  may define a cavity  340 . The cavity  340  may be located (e.g., centered) at an axis of rotation  360  of the bolt  310 . The cavity  340  may extend through the head  312 . The cavity  340  may extend partially into the shank  314 . The cavity  340  may define a top portion  344  and a bottom portion  348 . The top portion  344  may be hexagon-shaped. For example, the top portion  344  may be configured to receive the lower head  325  of the shear coupling  315 . The top portion  344  may be configured such that a torque applied to the shear coupling  315  (e.g., the upper head  320  of the shear coupling  315 ) is transferred to the bolt  310 . The cavity  340  may be configured to receive the screw  330 . For example, the cavity  340  may include internal threads  346  (e.g., female threads). The internal threads  346  of the cavity  340  may begin after the shear section  342 . When the shear coupling  315  is inserted into the head  312 , the orifice  350  may be aligned with the cavity  340  such that the screw  330  may be installed in the cavity  340  through the orifice  350 . 
     The screw  330  may include threads  332  and a head  334 . The head  334  may define a drive recess  336 . The head  334  may be a Phillips (e.g., crosshead) screw head. For example, the drive recess  336  may be configured to receive a Phillips-head drive. Although, the drive recess  336 , as shown, may be configured to receive a Phillips-head drive, the head  334  may be configured to receive another type of drive. For example, the head  334  may be configured to receive a flat head drive, a Torx drive, a square drive, a hex socket drive, etc. 
     The shear coupling  315  may be inserted into the cavity  340 . For example, the lower head  325  of the shear coupling  315  may be inserted into the top portion  344  of the cavity  340 . The screw  330  may be inserted into the cavity  340  via the orifice  350  in the shear coupling  315 . The threads  332  of the screw  330  may engage internal threads  346  in the bottom portion  348  of the cavity  340 . The captive shear bolt assembly  300  may be configured to be driven at the shear coupling  315 , for example, the upper head  320  of the shear coupling  315 . As torque is applied to the upper head  320 , the captive shear bolt assembly  300  may rotate as the threaded portion  318  engages complementary threads, namely, threads in opening  214  of fixed jaw  202  and threads in opening  226  of moveable jaw  204  so that when fixed jaw  202  and moveable jaw  204  are placed around insulator  104 , captive shear bolt assembly  300  is then rotated in the first direction to move captive shear bolt assembly  300  in the direction A, shown in  FIG. 18 , and stop ridge  338  of captive shear bolt assembly  300  moves moveable jaw  204  in direction A to move protruded side  222  of moveable jaw  204  closer to top member  210  of fixed jaw  202  moving two jaw faces  208  closer together connecting the modified clamp  1600  to insulator  104 . When the applied torque exceeds a threshold torque, the shear section  342  of the shear coupling  315  may shear such that the upper head  320  is mechanically decoupled from the threaded portion  318  of the bolt  310 . For example, when the shear section  342  shears, the upper head  320  may no longer drive the threaded portion  318  of the bolt  310 . When the shear section  342  of the shear coupling  315  shears, the screw  330  may captively secure the upper head  320  to the bolt  310 . For example, the screw  330  may engage the internal threads  346  in the bottom portion  348  of the cavity  340  such that the shear coupling  315  remains coupled to the bolt  310  when the shear section  342  has sheared. Similar to torque bolt  1606 , once a predetermined amount of tension is applied to the modified clamp  1600 , then captive shear bolt assembly  300  breaks along shear section  342 . This will ensure adequate tension is applied to the overall clamp  1600  as well as eliminate risk of overtightening. 
     The captive shear bold assembly  300  may be configured to be reused. For example, when the shear section  342  has sheared, the screw  330  may be removed such that the shear coupling  315  may be removed. A replacement shear coupling may be installed such that the captive shear bolt assembly  300  can be reused. 
       FIGS. 27-29  depict another example of a captive shear bolt assembly  500  that can be used with clamp  1600  instead of torque bolt  1606  in a modified clamp  1600 . Accordingly, the modified clamp  1600  is the same as clamp  1600  that is not modified except uses captive shear bolt assembly  500  instead of torque bolt  1606 . Captive shear bolt assembly  500  is the same as captive shear bolt assembly 500 of U.S. patent application Ser. No. 16/582,532 filed Sep. 25, 2019 that is hereby incorporated by reference except captive shear bolt assembly  500  adds a stop ridge  538  for moveable jaw  204  to rest on. Stop ridge  538  is the same as stop ridge  1638  of torque bolt  1606 . 
     The example captive shear bolt assembly  500  may include a bolt  510  and a shear coupling  515 . The bolt  510  may include a head  512 , an extension  513 , and a shank  514 . The head  512  may be hexagonal, for example. The head  512  may define a top surface  522  and a bottom surface  523 . The extension  513  may be cylindrically-shaped, as shown. The top surface  522  may be cylindrical, hexagonal, or some other shape. The extension  513  may define a cavity  508 . The shank  514  may extend from the bottom surface  523 . The shank  514  may include a shoulder  516 , a threaded portion  518 , and a non-threaded portion  524 . The shoulder  516  may be between the bottom surface  523  of the head  512  and the threaded portion  518 . The shank  514  may define a groove  517  between the shoulder  516  and the threaded portion  518 . The groove  517  may be configured such that the bolt  510  is retained within a tap connector, as described herein. For example, the groove  517  may be configured to receive a retaining ring (not shown). The threaded portion  518  may be located between the shoulder  516  and the non-threaded portion  524 . The non-threaded portion  524  may have a cross-sectional area that is less than or equal to a minor diameter of the threaded portion  518 . The non-threaded portion  524  may be configured to receive a fastener. For example, the shank  514  may define a cavity  521 . The cavity  521  may extend a distance L 1  from a distal end  526  of the non-threaded portion  524  into the shank  514  and may include internal threads  519 . The cavity  521  and the internal threads  519  may begin at a distal end  526  of the non-threaded portion  524 . The cavity  521  and/or the internal threads  519  may extend into the non-threaded portion  524  and the threaded portion  518  of the shank  514 . 
     The shear coupling  515  may define an upper head  520 , a lower head  525 , and a shear section  542 . The upper head  520  and/or the lower head  525  may be hexagonal-shaped. For example, the upper head  520  may be a first hexagonal nut and the lower head  525  may be a second hexagonal nut. The upper head  520  and the lower head  525  may be connected by the shear section  542 . The upper head  520  may be configured to receive an external torque. The shear coupling may be configured to transfer the external torque to the bolt  510  such that the bolt  510  rotates around its rotational axis when the external torque is applied to the upper head  520 . The shear section  542  may define a tapered cross section with a first diameter at the upper head  520 , a second diameter at the lower head  525 , and a third diameter at a midpoint between the upper head  520  and the lower head  525 . The first diameter and the second diameter may be equal. The shear section  542  may be configured to shear at or above a threshold torque. For example, one or more of the third diameter, the material, and/or the thickness of the shear section  542  may be determined and/or configured based on the threshold torque. 
     The shear coupling  515  may be configured to receive the extension  513  and the head  512 . For example, the shear coupling  515  may define an orifice  509 . The orifice  509  may extend through the upper head  520 , the shear section  542 , and the lower head  525 . For example, the orifice  509  may start at a top surface  552  of the upper head  520  and may terminate at a bottom surface  554  of the lower head  525 . The orifice  509  may be configured to receive the head  512 . For example, the orifice  509  may be hexagonal-shaped within the lower head  525  such that the head  512  is received within the orifice  509 . The lower head  525  may transfer an external torque to the head  512  of the bolt  510 . The orifice  509  may have different shapes and or sizes within the shear coupling  515 . Within the upper head  520 , the orifice  509  may be shaped similar to the extension  513  such that the extension  513  is received within the orifice  509 . For example, the orifice  509  may be cylindrical within the upper head  520 . 
     The shear coupling  515  and the extension  513  may be configured such that the shear coupling  515  can be attached to the bolt  510  using a tool. For example, the extension  513  may extend above an upper inner surface  541  of the upper head  520 . The upper inner surface  541  may be a shoulder defined within the orifice  509 . A tool (e.g., a punch) may be used to deform an upper portion of the extension  513  such that the upper portion  507  extends onto (e.g., partially onto) the upper inner surface  541  of the upper head  520 . For example, the tool may be forcibly inserted into the cavity  508 . The tool may be tapered such that the further the tool is inserted within the cavity  508 , the greater the upper portion  507  is deformed. The deformed upper portion  507  of the extension  513  may be configured to retain the shear coupling  515  to the bolt  510 . For example, the deformed upper portion  507  of the extension  513  may be configured to prevent the shear coupling  515  from being removed from the bolt  510 . 
     The captive shear bolt assembly  500  may be configured to be driven at the shear coupling  515 , for example, the upper head  520  of the shear coupling  515 . As torque is applied to the upper head  520 , the captive shear bolt assembly  500  may rotate as the threaded portion  518  engages complementary threads, namely, threads in opening  214  of fixed jaw  202  and threads in opening  226  of moveable jaw  204  so that when fixed jaw  202  and moveable jaw  204  are placed around insulator  104 , captive shear bolt assembly  500  is then rotated in the first direction to move captive shear bolt assembly  500  in the direction A, shown in  FIG. 18 , and stop ridge  538  of captive shear bolt assembly  500  moves moveable jaw  204  in direction A to move protruded side  222  of moveable jaw  204  closer to top member  210  of fixed jaw  202  moving two jaw faces  208  closer together connecting the modified clamp  1600  to insulator  104 . When the applied torque exceeds a threshold torque, the shear section  542  of the shear coupling  515  may shear such that the upper head  520  is mechanically decoupled from the threaded portion  518  of the bolt  510 . For example, when the shear section  542  shears, the upper head  520  may no longer drive the threaded portion  518  of the bolt  510 . When the shear section  542  of the shear coupling  515  shears, the deformed upper portion  507  of the extension  513  may captively secure the upper head  520  to the bolt  510 . For example, the deformed upper portion  507  of the extension  513  may be configured such that the shear coupling  515  remains coupled to the bolt  510  when the shear section  542  has sheared. Similar to torque bolt  1606 , once a predetermined amount of tension is applied to the modified clamp  1600 , then captive shear bolt assembly  500  breaks along shear section  542 . This will ensure adequate tension is applied to the overall clamp  1600  as well as eliminate risk of overtightening. 
     Referring to  FIG. 30 , guard assembly  10  can be modified to guard assembly  3000 . Guard assembly  3000  is the same as guard assembly  10  except guard assembly  3000  has first guard cover portion  12  and second guard cover portion  14  modified to first guard cover portion  3012  and second guard cover portion  3014  that connect to a pin  3100 , and, accordingly, the features that are the same for guard assembly  10  and guard assembly  3000  use the same reference numerals. Advantageously, pin  3100  is incorporated into first guard cover portion  3012  and second guard cover portion  3014  to retain them in relation to each other. Once installed, pin  3100  removes all risk of separation of first guard cover portion  3012  and second guard cover portion  3014 . 
     Referring to  FIG. 31 , first guard cover portion  3012  is the same as first guard cover portion  12  except first guard cover portion  3012  is modified to include a first hole  3015  and a second hole  3017  ( FIG. 32 ) and a first loop  3043 . Second guard cover portion  3014  is the same as second guard cover portion  14  except second guard cover portion  3014  is modified to include a third hole  3019  and a fourth hole  3021  and a second loop  3045 . First loop  3043  and second loop  3045  are each hot stick loops allowing for hanging above equipment, for example, power line assembly  100 , to locate as well as another attachment point to push down into the equipment if necessary/advantageous, and serve the same purpose as first loops  43  and second loops  45 . 
     Referring to  FIG. 33 , pin  3100  has a body portion  3102  connected to a ring portion  3104  by a connection portion  3106 . A ridge  3108  is formed between connection portion  3106  and body portion  3102 . Body portion  3102  has flexible members  3110  that each form a protrusion  3112 . A support member  3114  is inside of flexible members  3110  connecting a first portion  3116  of body portion  3102  to a second portion  3118  of body portion  3102 . Flexible members  3110  are flexible so that they can deform towards support member  3114  and are biased away from support member  3114  to maintain a shape shown in  FIG. 31 . 
     In use, guard assembly  3000  is installed the same as guard assembly  10  with the additional steps of connecting pin  3100  to first guard cover portion  3012  and second guard cover portion  3014 . Pin  3100  can be connected to first guard cover portion  3012  and second guard cover portion  3014  by using a hot stick. In addition, when second guard cover portion  3014  overlaps and clips by snap fit into first guard cover portion  3012 , which is the same as second guard cover portion  14  overlapping and clipping by snap fit into first guard cover portion  12 , first hole  3015  through first guard cover portion  3012  aligns with third hole  3019  through second guard cover portion  3014  and second hole  3017  through first guard cover portion  3012  aligns with fourth hole  3021  through second guard cover portion  3014 . Second portion  3118  of body portion  3102  of pin  3100  passes through third hole  3019  through second guard cover portion  3014  and first hole  3015  through first guard cover portion  3012 , and, then, passes through second hole  3017  through first guard cover portion  3012  and fourth hole  3021  through second guard cover portion  3014  so that flexible members  3110  pass through third hole  3019  through second guard cover portion  3014  and first hole  3015  through first guard cover portion  3012 . When flexible members  3110  pass through third hole  3019  through second guard cover portion  3014  and first hole  3015  through first guard cover portion  3012 , a force is applied to pin  3100  in a direction A so that flexible members  3110  deform inward toward support member  3114  allowing protrusions  3112  to pass through third hole  3019  through second guard cover portion  3014  and first hole  3015  through first guard cover portion  3012  positioning protrusions  3112  inside first guard cover portion  3012  and second guard cover portion  3014 . Once protrusions  3112  are inside first guard cover portion  3012  and second guard cover portion  3014 , then flexible members  3110  are biased outwards so that pin  3100  has a larger size at protrusions  3112  than third hole  3019  through second guard cover portion  3014  and first hole  3015  through first guard cover portion  3012  to maintain a connection between first guard cover portion  3012  and second guard cover portion  3014  unless a second force is applied in a direction that is opposite direction A that is strong enough to deform flexible members  3110  inward toward support member  3114  allowing protrusions  3112  to pass through first hole  3015  through first guard cover portion  3012  and third hole  3019  through second guard cover portion  3014  positioning protrusions  3112  outside first guard cover portion  3012  and second guard cover portion  3014 , which will allow first guard cover portion  3012  and second guard cover portion  3014  to be separated.
