Description: |
| The jaws are closed by a ratcheting tongs type action. The jaws are shaped to grip pipe or rods, as well as nuts. The ratcheting pawl has limited range of motion, so that fully opening the handles disengages the pawl to allow the jaws to be fully opened.
The tool includes a wire cutter in the jaws and a screwdriver on the end of one handle. |
