An outlet box (the term “outlet box”is also intended to encompass a junction box) mounting bracket useful for mounting an outlet box has slots to accept the shanks of outlet box mounting screws to eliminate the necessity of removing the screws when assembling the outlet box to one side of the bracket and a dry wall ring to the opposite side of the bracket. The bracket has an L-shape with right angled plate portions at one end, one of which plate portions is adapted to serve as a stiffening arm between the walls. At the opposite end, another flat plate portion is adapted to be secured to an extension plate in turn secured to a stud. In one embodiment, a recessed plate portion between the ends of the bracket contains the mentioned slots around an opening which registers with the interior chamber of the box and brings the outer surface of a dry wall ring in the same plane as the front outermost plane of the bracket. The extension plate has sets of holes enabling the bracket and thus the outlet box to be adjustably offset from the stud.

A single electrical outlet box stud offset mounting assembly, comprising: (a) a square outlet box having integrally joined base and sidewalls formed with a selected number and size of knock-out discs and on the outer edge of each sidewall of one opposed pair of said sidewalls having at least one inwardly-directed, laterally-spaced screw receiving tab with a threaded hole and positioned to provide at least one pair of diagonally opposite said tabs overlying an interior chamber formed by said box; (b) a dry wall ring having a central opening and a peripheral plate flange with screw clearance openings arranged for being mated to said tab threaded holes; (c) a mounting bracket comprising an L-shaped unitary mounting bracket formed of a single piece of stiff sheet material, including: (i) first and second contiguous rectangular plate portions in right angular relation at a first end of said bracket, said first plate portion being sufficiently wide to substantially equal the width of the interior space of the wall on which said bracket is installed to thereby serve as a stiffening member for said bracket; and (ii) a plate body portion extending outwardly from said second plate portion having: (aa) at an outer end a third rectangular flat plate end portion in the same plane as the plane of said second plate portion, said third plate end portion being adapted for securement to one end surface of an extension plate and having a pair of holes formed therein for receiving a mating pair of fasteners to effect said securement; (bb) between said third plate portion and second plate portion having a fourth rectangular plate portion in a plane offset from and substantially parallel to the plane of said second and third plate portions by an amount substantially equal to the thickness of a said dry wall ring flange, said fourth plate portion plane being established by parallel offsets formed on both sides of said fourth plate portion; (cc) an opening in said fourth plate portion substantially defined by opposed straight parallel upper and lower and opposed straight parallel right and left side edges and corner edges formed in said fourth plate portion around said opening, said opening being sized to register with the interior chamber of said box with the width of said opening being substantially equal to the spacing between a tab on one of said sidewalls and the opposite tab on another of said sidewalls; (dd) a first pair of laterally spaced screw slots matable with at least one of said tabs located adjacent a selected edge of said fourth plate portion opening; (ee) a second pair of laterally spaced screw slots matable with at least one other of said tabs extending from a second selected edge of said fourth plate portion opening opposite said first selected edge of said fourth plate portion opening, said second slots having a depth sufficient for at least limited box mounting adjustment on said bracket in the direction in which said slots are oriented and being positioned opposite to said first pair of slots; and (ff) a flange ring turning surface established by the spacing of said right and left edges of said opening from the said respective offsets on either side thereof and formed such that when a selected screw clearance opening on said dry wall ring rotates around a screw installed in a selected one of said tab threaded holes as another diagonally opposite selected said screw clearance opening is positioned to engage another diagonally opposite screw in another diagonally opposite said tab threaded hole, the bottom surface of said dry wall ring is able to slide on said fourth plate portion; (d) a plurality of screws adapted for being loosely fitted in said slots and for being secured in said tab threaded holes; and (e) a rectangular extension plate formed of a single piece of flat stiff sheet material with a stiffening arm at one end in right angular relation and sufficiently wide to substantially equal the width of the interior space of the wall on which said bracket is installed and having a plurality of sets of pairs of holes spaced lengthwise thereof located and adapted for receiving fasteners to secure an opposite end of said plate to the front surface of a stud utilizing one selected pair of said holes to establish the distance by which said bracket is offset from said stud and to secure said one end to said bracket third plate portion utilizing another selected pair of said holes in said plate mating a pair of holes in said bracket third plate portion, whereby when a said bracket has the third plate portion thereof secured to said one end of said extension plate and the opposite end of the extension plate is in turn secured to the front surface of a construction stud and fasteners are installed to perfect the securement and an electric outlet box is positioned adjacent the inner side of said fourth plate portion of said bracket in position with respect thereto so that the interior of said respective electric outlet box is accessible through the respective said fourth plate portion opening adjacent thereto and a dry wall ring is fixed to the other side of said fourth plate portion, said first plate portion tend to stiffen said bracket, said stiffening arm tends to stiffen said plate and said slots enable said outlet box, bracket and dry wall ring to be held in operative position with screws passed through said slots and secured in said tab-threaded holes with said tabs being oriented to mate with selected edges surrounding the respective said opening adjacent said box and whereby the outer surface of the flange of said ring is maintained when said screws are tightened in substantially the same plane as the outer surface of said second and third plate portions of said bracket on which said ring is mounted.
