A support for an electrical box, comprising a bar to be mounted between two spaced-apart wall studs or the like. The bar comprises an elongate web of sheet metal forming a front face of the bar and having side edges extending lengthwise of the bar, a pair of flanges extending rearwardly from the side edges of the web, and a forwardly-opening channel formed in the web running substantially the full length of the web between the side edges of the web. The channel has spaced apart side walls extending rearwardly from the front face of the web, a bottom wall connecting the side walls and forming the bottom of the channel, and pilot holes spaced along the bottom wall of the channel at relatively closely spaced and regular intervals whereby an electrical box may 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 over the channel and then fastening the box to the bar by using fasteners threaded through selected pilot holes in the bottom wall of the channel.
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 material forming a front face of the bar and having side edges extending lengthwise of the bar, a pair of flanges extending generally rearwardly from the side edges of the web, a forwardly-opening, generally U-shaped channel formed in the web running substantially the full length of the web between the side edges of the web, said generally U-shaped channel having spaced apart side walls extending generally rearwardly from the front face of the web, a bottom wall connecting the side walls and forming the bottom of the channel, and a plurality of preformed pilot holes spaced along the bottom wall of the channel at relatively closely spaced and regular intervals whereby an electrical box may 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 over the channel and then fastening the box to the bar by using fasteners threaded through selected pilot holes in the bottom wall of the channel.
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, a pair of flanges extending generally rearwardly from the side edges of the web, a forwardly-opening channel formed in the web running substantially the full length of the web between the side edges of the web, said channel having spaced apart side walls extending generally rearwardly from the front face of the web, a bottom wall connecting the side walls and forming the bottom of the channel, the side walls of the channel being generally parallel and the bottom wall of the channel being generally planar, and pilot holes spaced along the bottom wall of the channel at relatively closely spaced and regular intervals whereby an electrical box may 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 over the channel and then fastening the box to the bar by using fasteners threaded through selected pilot holes in the bottom wall of the channel.
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, a forwardly-opening generally U-shaped channel formed in the web running substantially the full length of the web between the side edges of the web, 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 means spaced inwardly from said free outer end portion defining a first fold line extending generally transversely of the extension and means spaced inwardly from said first fold line defining a second fold 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 at said first fold lines to form said fastening flaps, and if a shallower electrical box is to be attached to the bar, the extensions are adaPted to be bent at said second fold lines to form said 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 over the channel and then fastening the box to the bar by using fasteners threaded into said channel.
