Description: |
A single tooth on the inside of the movable jaw acts as a fulcrum point allowing the jaw to rock. A rack of teeth on the edge of the main bar provides the range of adjustment and a tension spring on the back side of the movable jaw holds the pivot tooth in position on the rack. Gripping teeth are cut on both jaw faces. |
