Abstract: A storage rack assembly comprises a rack (10) formed of a base (20) and U-shaped wires (21) forming side supports in which the rack (10) is used for storing articles such as audio and video cassettes (14, 12) and compact disc containers (16) on shelves, cabinets and the like. The U-shaped wires (21) are parallel to each other and extend transversely across the rack (10) in spaced relationship. The rack (10) may be of a knockdown type. Specifically, the wires (21) may have laterally extending feet (30) that removably fit within channels (78) in the base (20) so the rack (10) can be assembled and disassembled. A track (34) slidably mounts the rack (10) for sliding movement with the rack (10) and is mountable on a shelf or in a cabinet. The cassettes (14, 12) and disc containers (16) lie vertically between the wires (21) and across the base (20), resting on step portions extending along the longitudinal sides of the base. The step portions accommodate storage of various sizes of cassettes and discs (14, 12, 16).
