Description: |
| A quick adjust pipe and nut wrench -- the coil spring closes the jaws. The rotating sleeve has threads on a small portion of the interior corresponding to the flat portion of the shank. In use, hand pressure on the end of the shank compresses the spring to open the jaws. After the wrench is in place on the work piece, a partial turn of the sleeve handle tightens the grip and holds the adjustment. |
