Support for an electrical box

A support for an electrical box, comprising a bar adapted to be mounted between two spaced-apart wall studs or the like, said bar comprising an elongate web of sheet metal forming a front face of the bar and having side edges extending lengthwise of the bar, and elongate extensions of the bar projecting generally forwardly from said web at opposite ends of the bar and having free outer end portions bent to form fastening flaps extending laterally outwardly away from one another and generally parallel to the web of the bar, said flaps being adapted for engagement with said studs and securement thereto by fasteners, each extension having first narrow slot means spaced inwardly from its free outer end and defining a first fastening flap bend line extending generally transversely of the extension, and second narrow slot means spaced inwardly from said first bend line and defining a second fastening flap bend line extending generally transversely of the extension whereby, if a relatively deep electrical box is to be attached to the bar, the extensions are adapted to be bent along said first slot means to form relatively short fastening flaps, and if a shallower electrical box is to be attached to the bar, the extensions are adapted to be bent along said second slot means to form longer fastening flaps, said electrical box being adapted to be attached to the bar in a selected position lengthwise of the bar by placing the back wall of the box flush against the front face of the web and then fastening the box to the bar.
