Abstract: A shelving unit comprises a pair of side panels each having a front edge and a rear edge with the edges formed into generally C-shaped channels defining vertical upright support members. A plurality of vertically spaced slots are provided in each support member defining a plurality of vertically spaced rails. A pair of notches are formed in each rail. A shelf is provided with outwardly extending hooks on opposed edges thereof for cooperation with the notches of the support member rails. The shelves are thereby supported by the support members and may be adjusted to any desired pre-selected height.
