Strut

An elongated strut having a generally flat back wall, side walls parallel to each other at least at the top section thereof, inturned lips from said side walls, and a continuous slot along the length of said strut between said lips, said elongated strut also having inwardly depending flanges disposed generally continuously along the length of said slot, said flanges formed to receive and secure fittings inserted into said slot and engaged with said flanges, whereby said fittings are removably secured by said flanges inside said strut and a first portion of each of said inwardly depending flanges projects generally toward the interior side wall of the strut adjacent to said flange and an end portion of each flange projects generally toward the interior back wall of the strut and toward the other flange wherein said inwardly depending flanges define an interior cavity with a cross-section having at its widest point a width greater than the width of the continuous slot of said strut.

An elongated strut having parallel side walls, a generally flat back wall and a pair of opposing flanges depending inwardly from the lips of said strut along the length of the continuous slot of said strut wherein the upper portions of said flanges are disposed in the interior of the strut below the top surface of the lips of the strut, and the end portions of said flanges are angled away from the side walls of the strut toward each other and toward the back wall of the strut whereby said inwardly depending flanges define an interior cavity with a cross-section having at its widest point a width greater than the width of the continuous slot of said strut, said inwardly depending flanges having a configuration to removably secure a generally rectangular member.
