ABSTRACT:
An integral locking arrangement adapted for inclusion in different adjustable storage racks. Columns having rows of spaced apertures are interconnected by beams that carry suitable connectors, e.g., transverse lugs which are inserted into appropriate apertures. Downward movement of the lugs creates a camming action that solidifies the connection and aligns an integral locking tab with an aperture. Displacement of the locking tab causes its head to reside in an aperture in the column and prevents upward disengaging movement until the locking tab is withdrawn.
