Abstract
Abstract A work bench work surface extension apparatus comprises first, second, third and fourth extension members. First and second releasable attaching means releasably attach one end of each of the first and second members to one side of a work bench work surface such that the opposite ends of the members extend across the surface and project outwardly from its opposite side. Third and fourth releasable attaching means releasably attach one end of each of the third and fourth extension members to the opposite side of the work surface, such that the opposite ends of the third and fourth members project outwardly from that opposite side of the work surface. A work surface extension member can thus be supported between the extension members.
