ABSTRACT:
A ceiling mounting assembly for holding electrical devices in place on a joist that includes an electrical box having a base of three planar surfaces, each planar surface at a different depth, a first fastener device for temporarily securing the electrical box in place, a ceiling medallion for covering the electrical box, a second fastener device for temporarily securing the ceiling medallion to the electrical box, and a fixation device for securely fastening the electrical box and the ceiling bezel to the joist. The electrical box for mounting on the joist includes a generally rectangular housing with two opposite sides having a stepped appearance defining three different depths of the housing with a third side at a first shallow depth and a fourth side at a third deepest depth, a first back piece spanning the opposite sides at a first depth approximately equal to the thickness of one half inch wall board, a second back piece spanning the opposite sides at a second depth greater than the first depth of the first back piece, the second depth approximately equal to twice the thickness of one half inch wallboard and a third back piece spanning the opposite sides and at a third depth greater than the second depth of the second back piece.
