Abstract
Abstract Upper and lower rails are spaced from one another and each comprises at least one major longitudinal surface with openings provided in the major surfaces. At least one upright rail support member interconnects the upper and lower rails and connecting portions of this support member extend at least in part into the openings and are wedgedly connected to the respective rails. Anchoring members for anchoring the thus assembled rail are provided at longitudinally spaced locations of the rails.
