In other embodiments, mounting plate  48  may be rotated in either the clockwise or counterclockwise direction such that bottom edge  77  is at an angle ranging between 0 to 90 degrees relative to bottom edge  79  of backing plate  76 . For example, in certain instances, bottom edge  77  of mounting plate  48  is rotated clockwise or counter clockwise to an angle of generally 45-75 degrees with respect to bottom edge  79  of backing plate  76  and vertical axis V. In other instances, bottom edge  77  of mounting plate  48  is rotated to an angle of generally 90 degrees with respect to bottom edge  79  of backing plate  76  and vertical axis V. The number of the plurality of fasteners  72   a - c  may be varied in different embodiments. Similarly, the number of openings for each the plurality of openings  70   a - h  of mounting plate  48  and the plurality of openings (not shown) of backing plate  76  are variable. 
       FIGS. 6A-6D  illustrate various illustrative embodiments of cross-sectional profiles of groove  56  of door  54 . In each of the embodiments, groove  56  and mounting plate  54  are comprised of two distinct layers comprised of retention element  68  and a layer  61  comprised of a structural material defining the outer surface of door  54 . This can include, but is not limited to, a metal or a plastic material. In the embodiment of  FIG. 6A , the cross sectional profile of groove  56  is defined by at least one rounded surface and, illustratively, generally defines a semicircular profile. The semicircular shape of groove  56  may have a radius  57  that is generally constant. In other embodiments, radius  57  of the semicircular groove  56  may be variable. 
     With respect to  FIGS. 6B-6D , groove  56  may include at least one linear surface. For example,  FIG. 6B  illustrates an additional embodiment of the cross-sectional profile of groove  56  such that the cross-section is generally square. In similar embodiments, the cross-sectional profile of groove  56  may be generally rectangular.  FIG. 6C  illustrates an additional embodiment of the cross-sectional profile of groove  56  such that the cross-section is generally triangular. 
     Additionally,  FIG. 6D  illustrates another embodiment of groove  56  such that the cross-sectional profile is semi-hexagonal. The cross-sectional profile of groove  56  is not limited to these illustrative embodiments and may comprised of varying shapes, including but not limited to, a semi-ellipse or pentagonal shape. The ability to vary the shape of the groove  56  is advantageous such that different tools can be fit securely within the groove  56  of the support assembly  40  because various surfaces of the tools/accessories may be frictionally retained against the linear surfaces defining groove  56 . 
       FIGS. 7-10  illustrate additional embodiments of support assembly  40  configured such that multiple tools  42 ,  43  may be held by support assembly  40  simultaneously.

In embodiments, second clamping mechanism  90  is configured to retain both first groove  96  and second groove  98  to door  56 ′″ and/or mounting plate  48 . In this way, support assembly  40 ″″ can be configured to hold at least three tools simultaneously. For example, first groove  96  is configured to hold a tool, second groove  98  is configured to hold a tool, and a tool may be held between mounting plate  48  and door  56 ′″. It may be appreciated that because support assembly  40 ″″ includes separate hinge assemblies and clamping assemblies associated with grooves  96 ,  98 , various tools/accessories may be accessed from any of grooves  96 ,  98  and/or at door  56 ′″ independently of each other while other tools remain secured within support assembly  40 ′″. Further, with respect to the illustrative term “groove” used herein, it is to be appreciated that “groove” defines any retention feature configured to support a tool or accessory on support assembly  40 ″″ and is not limited to any structural definition of “groove.”
