Abstract: Each panel includes a pair of fibrous glass boards mounted in a generally rectangular frame having an inner peripheral flange between the fibrous glass boards and having five outer peripheral grooves for receiving finish fabric anchoring beads, generally semi-circular hollow moldings having finish fabric anchoring grooves, spaced cam members interlockable with those of an adjacent panel, and shelf bracket standards. Each panel has a pair of supporting legs and base side panels with snap-on connections to the legs. An alignment plate connects adjacent legs of adjacent panels and receives a post with a stabilizing foot extending transversely to the panels.
