Description: |
| The spring serves as an adjustment lock by binding against the monkey wrench's adjusting rosette. The thumbscrew has a "t" cross rod which lifts the spring off the rosette to allow free movement to change the adjustment. This was conceived as an add-on which could be applied to any monkey wrench. |
