ABSTRACT:
A work support bracket is improved by providing it with brace members having a cross sectional shape. The brace members are fixed to first and second horizontal socket members respectively such that the upper horizontal segments of the brace members extend away from one another. The lower, central regions of the vertical segments of the brace members are notched to straddle the first and second horizontal socket members respectively. The outward, central regions of the upper horizontal segments are notched to define elongated pathways extending through first and second generally vertical socket members respectively and through said notched outward central regions respectively. The lower horizontal segments of the brace members are first and second pairs of tab members which extend from opposed ends of the first and second brace members respectively. The first pair of tab members is coplanar with the upper surface of the first horizontal socket; and, the second pair of tab member assumes a position coplanar with the first horizontal socket, when the first and second horizontal sockets are interconnected. The lower horizontal segment of the second brace member has a third tab member which extends atop the second horizontal socket member, coplanar with the first horizontal socket, when the first and second horizontal socket members are interconnected.
