Abstract: Boltless shelving apparatus is described which comprises a number of upright support members (10), and a number of transverse shelf members (12). The shelves are mounted to the supports by insertion of downwardly extending engagement members (32) at the shelf corners into corresponding slots (20) in the uprights. The engagement members and slots preferably both have a generally "L" shaped cross-section, and the shelves may be mounted to the supports simply by downward movement of the engagement members into the slots.
