Abstract
Abstract The invention relates to a corner support for a shelving system of the type described in Canadian Patent No. 1,030,905. The corner support is generally triangular in shape when seen in top view, and has a rear end formed on one leg of the triangular shape and a front end formed on another leg of the triangular shape. Vertically spaced bars are disposed in the rear end to engage with holding notches of the corner posts of the shelving system, and the front end receives a downwardly depending portion of a corner of a shelf. Thus, the corner support is held at and by the corner post, and in turn, holds a corner of the shelf.
