<p>A universal support bracket attaches to different sizes of electrical boxes and holds a box rigidly within a hollow wall structure having different depths. The bracket comprises a flat elongate strip of sheet material, one end of which has an engagement hook to engage a side wall of the box, an arm at the one end has a first flange which may rest on the inside surface of a wall board to position an electrical box recessed from the outside surface, or the arm may be bent at a bend line so that the bent portion rests on the inside surface of a wall board to position a box substantially flush with the outside surface of the wall board. The strip has a plurality of locking tongues, each having a bend line so that when at least one of the tongues is bent, it locks the bracket to the box, and the other end of the strip has a series of bend lines spaced apart across the strip, such that a portion of the strip may be bent perpendicular to the strip to accommodate different depths of hollow wall structures.</p> |
