Description: |
| A ratchet socket driver that uses a pivoting grip action rather than a pawl and teeth. The pivot pin for the handle can be unscrewed and the handle flipped over to reverse the direction of the grip. The wrench includes features for fixed or swivel handle, and alternatives for fixed size or adjustable sockets. |
