   BACKGROUND OF THE INVENTION 
   Field of the Invention 
   This invention relates generally to pre-wiring installation systems, and in particular, to a universal low voltage pre-wiring system designed for applications including, but not limited to, residential alarm or smoke detection systems, home entertainment speaker and control systems, residential inter-communications systems, HVAC thermostats, residential security systems, surveillance systems, watering and drip irrigation systems, and the like. 
   BRIEF SUMMARY OF THE INVENTION 
   During construction of a dwelling or building, it is useful to install electrical wiring between outlet boxes, junction boxes, switches, fixtures, control devices, and the like by pre-wiring to actual or potential terminals after structural support members are in place. This pre-wiring process is made easier due to the fact that various wall portions are framed with internal structural elements and these structural elements are subsequently covered and finished with external surface elements. Designated terminal locations for such installed wiring can be easily mounted to the internal framing elements prior to completion of the external wall portion and suitable wiring interconnects and channels may be installed by extending the locations through the space designated for exterior or exterior wall finish. To the extent that such interconnects are components of a pre-wiring system, great flexibility in pre-wiring and finished wall wiring location is possible. When such components are modular in design, pre-wiring assembly is easy and inexpensive. Installed trim elements of pre-wiring systems can be painted over so the pre-wire terminal location blends into any wall or ceiling location. 
   It is, therefore, one object of this invention to provide a new and useful system, apparatus and method to allow the pre-wire routing of low voltage electrical pathways in a building during construction so that additional outlet boxes, junction boxes, switches, fixtures, and the like may be installed without compromising the integrity of the exterior surfaces of the walls containing such terminal locations. 
   A further object of the present invention is to provide a cost effective system, apparatus and method to allow the pre-wire routing of low voltage electrical pathways in a building during construction so that users obtain a professional quality installation. 
   It is yet another object of this invention to provide a universal system, apparatus and method to allow the pre-wire routing of electrical pathways applicable to all low voltage systems. 
   It is a further object of this invention to provide an inexpensive system, apparatus and method for pre-wire routing of low voltage electrical pathways. 
   It is yet a further object of this invention to provide a system, apparatus and method to eliminate the necessity of obvious wire location plates and make pre-wire locations undetectable on an interior finished wall surfaces. 
   Apparatus according to the present invention is thus adapted for pre-wiring a building during construction whereby electrical wire or the like may be drawn as an electrical interconnect between along a pathway between a first and second terminal locations in a wall portion of a building such that the terminal location on the finished wall portion is undetectable. In its broad form, this apparatus includes in combination a hanger, a grommet, a Sheetrock® tool and trim located in the finished wall portion. The grommet is secured by a lock nut on the inside portion of the apparatus between studs or rafters. Embodiments of the apparatus are suitable for corner locations, exterior surfaces, and angled surfaces where weatherproofing issues or geometric anomalies are presented. 
   In a preferred embodiment of the apparatus, system and method of the present invention, a hanger having at least one opening is installed between rafters or on a stud. A grommet having a continuous annular aperture comprising an inner surface of even diameter, a first threaded male open end, a second threaded male open end, and cylindrical flange of predetermined diameter attached midway thereto such that the flange end corresponds to, and is flush with, the end of the second threaded male open end, is provided. The grommet is installed into an appropriate hanger opening and secured to the hanger by a lock nut threaded onto the first threaded male open end on the rafter or stud side of the hanger. The wire is run to the grommet. The grommet second threaded male open end and flange extends from the finish side of the hanger. A Sheetrock® tool having a threaded female open end, correspondingly threaded to communicate with the grommet second threaded male open end, within a cylindrical flange of diameter slightly less than the grommet flange, and a tapered ribbed male open end, defining an interior passage through the tool of even diameter is provided. Once the Sheetrock® tool is threaded onto the grommet second threaded male open end, the wall is finished with drywall and textured. A trim having a cylindrical flange with open end of a diameter slightly larger than the grommet flange and locking mechanism within the trim cylindrical flange is provided. The Sheetrock® tool is then removed from the grommet and the trim is installed and locked onto the grommet flange. 
   Related features, objects and advantages of the present invention will be apparent with reference to the following description and accompanying drawings.

A weatherproof gasket  28  or  40  is installed onto the weatherproof flashing flange  26 B, and trim is screwed onto the threaded male open end  26 C,  FIGS. 3 and 16 . The exterior wall and trim are painted according to the construction specifications. 
   The principal components of the apparatus of the present invention, namely the grommet  16 , Sheetrock® tool  18 , trim  20 , lock nut  12 , rafter bracket  14 , corner bracket  22 , corner trim  24 , weatherproof flashing stub  26 , weatherproof trim  30 , clip stick  32 , stud bracket  34 , gasket  28 , and slope gasket  40 , and all sub-component elements thereof, are made of plastics selected in consideration of the intended field of application of the pre-wiring installation and it is significant in this respect whether the component or sub-component elements thereof should be rigid or flexible. It has been found that adequate plastic materials of construction for these components and sub-component elements include, inter alia, poly-vinylchoride, polyethersulfones, and polyetherketones suitable for Cat 5 or Cat 6 wiring. Further, rafter bracket(s)  14  and stud bracket(s)  34  may be made from suitable metals according to construction specifications. 
   It is further understood that the application of the invention is not restricted to the field which has been explained with reference to the illustrated embodiment. The invention can be applied to advantage not only to pre-wiring low voltage connections, but to connections for fiber optic wiring, and the like. Besides, trim  20  locking mechanism  20 C detents [and related locking mechanism  24 C detents for the corner trim  24 ] are not restricted to the preferred embodiment number [two] and spatial orientation [one hundred eighty degree orientation, one to the other], but could number three detents with one hundred twenty degree spatial orientation, one to the other immediately adjacent mechanisms on the same plane perpendicular to the defined central longitudinal axis of the trim, four detents with ninety degree spatial orientation, one to the other immediately adjacent mechanisms on the same plane perpendicular to the defined central longitudinal axis of the trim, or similarly modified detent number and arranged orientation. Other locking mechanisms, such as rings, may be substituted for detents in keeping with the scope of the present invention. 
   As can be seen from the foregoing, a the present invention can be installed and utilized to quickly provide pre-wire routing for low voltage electrical pathways in a building during construction so that additional outlet boxes, junction boxes, switches, fixtures, and the like may be installed after finishing without compromising the integrity of the exterior surfaces of the walls containing such terminal locations.
