Abstract
An adjustable shelf system is disclosed having vertical left and right end panels, one or more center panels, top and bottom panels for holding the end panels and center panels in spaced relation and a back panel. A plurality of shelves may be adjustably positioned at various levels between the end panels and center panels. Each of the end panels and center panels is formed with support loops that are interlockably engaged by insertable tabs formed on the left and right sides of each shelf. Alignment tabs on each shelf side defined common left and right lower edges that guide the shelf into its proper position during assembly and subsequent re-positioning. The support loops on opposed vertical panels (e.g., the left end panel and the center panel) are structurally different and unique to the left and right sides of the shelf, respectively, so that the shelf can be insertably mounted in only a single orientation and at the proper depth within the shelf system.
