Self-energizing lower jaw provides 3X more gripping power than traditional locking pliers, with no slipping or stripping. Provides maximum torque without requiring heavy input pressure – jaw mechanism naturally grips tighter as more torque is applied to the tool. One-handed, triggerless release is 2X easier to open than traditional locking pliers. Anti-pinch, non-slip ProTouch™ Grips provide comfort, control, and less hand fatigue.
