Are the GrooveLock and ProTouch pliers tested?

Yes, the GrooveLock Pliers go through a series of 12 tests ranging from the Extreme Load test that tests the amount of force which can be applied to the handles to a test that measures the amount of twist the product will withstand.

Our ProTouch" pliers all meet or exceed all applicable ANSI/ASTM (USA) and DIN (Germany) specifications.
