ABSTRACT:
A plastic leg for a washtub is constructed from a flat rigid preform having a pair of spaced apart grooves extending the length of the preform. The grooves form living hinges allowing the preform to be folded into a prism shape of triangular cross section. One edge of the preform carries a plurality of tabs which fit through apertures located in the opposite edge of the preform. Alternate oppositely extending shoulders on the tabs lock them in place thereby maintaining the preform in its folded condition to form a leg. The upper part of the leg is adapted to be attached to a washtub while the bottom of the leg carries a leveling screw.
