LockJaw Self-Adjusting Pliers
Self-adjusting Vise Grips
These tools work similar to ViseGrips except they automatically adjust to the size of the object they’re gripping. The tension desired is adjustable via a set-screw, but once the tension is set, different size objects can be clamped without readjustment.
Also, the release lever is opposite that of the ViseGrip in that you pull on the lever with your ring finger while maintaining full grip of the pliers. No more pliers flying across the room and no more pinched fingers between the release and handle!03/1/18
