They also can clamp workpieces in series by using the back surfaces of the clamps to locate the next workpieces. Clamp height adjusts by the depth of the milled slot that locates the clamp. They are available in two sizes with holding forces of 6,000 lb. and 12,000 lb. The hardened and ground clamps are recommended for use on work cubes and machine tables with tapped holes or T-slots.
