ABSTRACT OF THE DISCLOSURE 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.
