    Abstract: A two-way dual action clamp for accurately clamping together two or more workpieces. The clamps are particularly useful in temporarily clamping together two European style wall cabinets prior to permanently joining the units together with a plurality of screws. Each clamp has two jaws, one L-shaped and one I-shaped which, when assembled form a U-shape. The jaws are manipulated by a hand operating screw so as to clamp together workpieces such as abutting sides of frameless cabinet units. A second hand operating screw carries a pressure plate and extends transversely through a threaded opening in the bight portion of the U-assembly. The pressure plate acts to bring edges of the cabinet units into flush relationship. The distal ends of the jaws are provided with spring actuated workpiece engaging and retaining cams which are spread apart to a limited extent when workpieces are inserted between them.
