How it Works!

When the Lock Screw is tightened into the lock screw detent of the insert, three directional insert clamping occurs. Clamping force is up against the end of the J-LOC master jaw, back against the Lock Pin and securely in contact with the side of the tongue. This creates a no clearance situation to insure rigidity and repeatability.
