Abstract
Abstract A small generally flat body member of square configuration has slots extending diagonally from the four corners toward the center of the body member. The slots are elongated and widen into a socket portion at the inner end, to receive and tightly fit a flat member such as plate glass in a shelving assembly. The body member has openings through the center and in the four quadrants for stress relief and use in receiving dowels in assembly. The side of the body and the slots are rimmed, and set pins corresponding to the slots are provided, the pins having corresponding rims for sliding into the slots to increase the rigidity of the body member.
