Abstract

A mounting bracket for supporting an electrical box or other electrical device to a wall stud is adapted to contact an opposing wall to resist movement of the bracket. The bracket includes a front plate and a support plate extending perpendicular to the front plate and having a length to engage the opposing wall. The extension plate is integrally formed with the support plate and can be folded to an outward extended position to increase the effective length of the stabilizing plate to accommodate wall cavities of different depths. The extension plate includes fold lines so that an end portion can be bent to shorten the effective length of the extension plate.
