Description: |
| The patented feature is a release mechanism that allows free movement of the adjusting nut on a steep-pitched thread adjustable wrench. The single-jaw versions have a jaw extension which is a "hook" to move the jaw, and the release mechanism is a rod extending back into the handle. The combination allows for one-handed operation & adjustment.
The double-jaw version has lever pawls that hold the adjusting nut from turning. |
