Abstract: A shelving system and components thereof is disclosed. Preferably, the shelving system is a reverse cantilever shelf mounting system, wherein one or more shelves are supported by and extend rearwardly from an inner face of upright vertical standards. The vertical standards are of two piece construction having a triangular cross-sectional shape and an inner face having vertically oriented slots along its length for mounting shelf brackets. Tensioned cross braces lock together welded side frames of the shelving system. A base facia or “kick plate” panel may be mounted to the base of the shelving system frame, and optional open-sided rod bookstops mate with punched out mounts that are integral with the shelf top surface to securely mount the bookstop to the shelf.
