Releasing the cam allows the spring loaded jaws to move back for loading and unloading of the workpiece. The cam is activated with a hex wrench and eliminates workpiece interference. Mounts from the top with two low head cap screws. The jaws and cam are made from hardened 4140 alloy steel. The body is made from 1045 alloy steel. Black oxide finish.
