A bracket has a base or back that can be attached to a support, and spaced-apart, substantially vertical projections or flanges extend out from the back. The flanges are load-bearing and spaced apart to leave two side-by-side U-shaped recesses of unequal width. The recess of greater width is dimensioned to receive the two flanges that define the recess of lesser width when an identical and second bracket is positioned opposite the first and the flanges of the two brackets interfitted. Thus, a bracket pair is formed with their wide and narrow recesses being interfitted. At the bottom of the narrow recess, a captured nut on an apertured tab is positioned to receive a threaded screw or bolt from above. A strip with holes bridges the upper edges of the flanges of both brackets of the pair and screws can be passed through the holes between the flanges to engage the nuts at the lower ends of the narrow recesses.
A bracket for attachment to a support comprising a metal strip having upper and lower edges, a back between those edges and at least three load bearing flange projections extending outwardly from said back, said projections being spaced apart from one another and at least two U-shaped recesses being formed between the projections, when said bracket is viewed in plan, said projections extending substantially vertically between said upper and lower edges, a first of said recess being greater in width than a second of said recesses and a middle projection being a side common to both of said recesses, said first recess being dimensioned to receive the second recess, together with the corresponding side projections, of an identical bracket when the projections of the two brackets are interfitted with one another to form a pair of opposing brackets.
