Description: |
| This patents covers an add-on to Jorgensen 3600 and 3700 series F clamps to provide a sort of "Quick Grip" capability: squeezing the handle moves the clamp-head forward slightly, tightening the clamp while needing only one hand. Once the clamp is sufficiently tight that the workpieces won't move, the regular screw-handle can be used to fully tighten the clamp. |
