These thickness gauge holders provide a handy, convenient means of rigidly holding single leaves or strips of thickness gauge stock of any thickness from 0.001-0.025". Stock up to 6" long is easily inserted in the holder and firmly gripped in the desired position by a cam lock. This permits all of the stock to be used, because as it wears from use, the defective end can be snipped off and new stock pulled out until entirely used up. Clamp stock at one end. Dull nickel finish.
