BenchJaws™ from Rockwell is a hands-free bench vise that mounts to the corner or center of any standard workbench and can support up to 220 pounds of load. Foot-activated clamping jaws leave both hands free, and the two-position mount allows repositioning within 90 seconds. It has a clamping range of 0" to 16". The RW9208 Multipurpose Jaw self-aligns to tapered, round and irregularly shaped objects and is priced around $130.
