A modular "knock-down" type shelving system having adjustable height shelves includes a plastic support post having a generally right equilateral triangular cross-section. The support post is composed of pultruded thermosetting plastic having unidirectional E Glass fibers extending therethrough and a thermoplastic coating bonded to the outer surface thereof. The inner surface of the interior side of the support post is bowed outwardly. As a result, when a wedge member is disposed on the interior side of the post and the support post and wedge member combination supports by wedge action a sleeve comprising an end beam and a collar, the interior side of the support post is urged outwardly and is supported by the wedge member. The collar is locked to the end beam when a tongue of the collar passes through a slot in the end beam into a rotatable lock in a blind hole in the bottom of the end beam. A plurality of shelves are adapted to be snap-fit over a rectangular support structure comprising two end beams, and two side beams and a center beam connecting the two end beams. In this manner the shelf can be easily assembled and disassembled and supported on a support post at a predetermined height.
