Abstract
Abstract A utility box adapted to be mounted to the surface of a wall. The box provides an electrical outlet connection and is comprised of a back surface mounting plate adapted to be screwed to the wall surface without cutting into the wall. The mounting plate has a pair of tabs at one end and retaining flanges at an opposite end for interfitting with the box housing with the tabs fitting through opening at one end of the housing and the retaining flanges being screwed into the opposite end of the housing. Conduit knockouts are provided at the box so that the conduit may be fitted into the box and provisions are made for the connection of a faceplate to the box having any desired type of control switch through a simple screw connection of the plate to screw holes provided in the front of the box.
