Description:

The threaded adjusting ring is connected to the movable jaw in a positive fashion to apply positive adjustment in both directions. The fixed and movable jaws have holes near their outside ends. This allows the jaws operate as a screw-adjust nut wrench, and as holders for wire twist-tightening hose clamps.
