An adjustable hanger assembly is disclosed for mounting and supporting an electrical box between a pair of structural supports, such as studs or joists. The adjustable hanger assembly is designed to properly position electrical boxes of different depths between the structural supports such that the open end of the electrical box is flush with the exterior surface of the wallboard or plasterboard, e.g., dry wall or sheet rock. The adjustable hanger assembly has a pair of telescoping support members slidably coupled together and a hanger strap fixedly coupled to an electrical box. The support members are preferably tubular with a rectangular transverse cross-section. One side of the support members acts as a positioning edge for maintaining the open end of an electrical box of a first depth flush with the exterior surface of the wall board. Each of the support members has a pair of positioning flanges with their free ends acting as positioning edges and a third side with no flange acting as a positioning edge for selectively maintaining the open ends of three different depths of electrical boxes flush with the exterior surface of the plasterboard, depending on which of the positioning flanges are used. |
