An electrical box support assembly for stud wall construction includes two channel shape struts with one being confined by and telescoping in the other. Both have a longitudinally extending V-shape groove opening toward the box or boxes to be supported thereon whereby the boxes may quickly be attached by a self tapping screw with a screw gun. The groove ensures that each box is straight and, if more than one box is mounted, both straight and aligned. While the two parts may be telescoped they are not readily separable and are sufficiently rigid so that they do not need to be preassembled. The opposite ends of the struts are each provided with planar tabs with two longitudinally spaced designed bend points at which the strut ends or tabs may selectively be field bent to form right angle flanges matching the depth of the box to be supported. The tab ends of the struts are shipped straight or flat and in some forms may include one or more additional bend points which, when the strut end tab is selectively bent, may be used to form a flange substantially parallel to the strut. The parallel flange may be the full width or one-half the width of the stud. The field formed flanges may be provided with holes to facilitate the screw gun fastening of the strut ends to substantially any surface of the stud. If a projecting portion of the tab is not employed, it may simply be folded back on itself to form a double thickness end.
An electrical box support for stud wall construction comprising telescoping overlapping struts forming an adjustable width horizontal strut assembly, each strut having a face to which the electrical box may be secured, bendable tabs on the end of each strut in the same plane as the face adapted to be shipped flat and field bent to enable the ends of each strut to be secured to studs, and means located on the tabs to facilitate the field bending of each tab at at least two different locations whereby a flange formed by the bendable tab may vary to support electrical boxes of different depth substantially flush with the edges of the studs.
An electrical box support in stud wall construction comprising a horizontal strut formed of telescoping members having a V groove along the center of the face thereof, to which a box is secured, and field bendable tabs at each end of said strut and in the same plane as the face of the strut adapted to be shipped flat and field bent to enable the ends of the strut to be secured to studs, and means located on the tabs to facilitate the bending of said tabs at two different locations whereby the length of the field bent tab may vary to form a flange to support boxes of different depth substantially flush with the edges of said studs.
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 fastener receiving 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.
