Description: |
| A spring-loaded lever with gripping teeth on a cam engages rack teeth on the main shank to hold the adjustment. The shank has rack teeth on two edges. The movable jaw can be slid off the handle and turned 180 degrees to switch from the nut gripping jaw to the pipe gripping fixed jaw. The extended lever can be gripped together with the handle to insure the adjustment does not slip. |
