An electrical box support is provided having a set of struts telescoping one within the other to accommodate the length for attachment to studs of different spacings. Each strut has a face suited for mounting an electrical box and has a series of inwardly directed, uniformly and relatively closely spaced detents. The detents serve both for releasably locking the length of the support and for guiding the entry of screws used to attach the box to the support. Each strut has an end tab adapted for bending to mount to the studs in a position established so that a mounted electrical box appropriately meets the surface of a wall board to be installed. Bending in a controlled straight line is accomplished by the formation of discontinuous score lines.A second embodiment of the invention is formed with two struts having end tabs and a third strut having no end tabs and engaging the other two struts. Either one or both of the struts with end tabs can be moved to change the length of the assembly. The assembly length is releasably locked by a series of mating detents.
