Description: |
| The movable jaw can be adjusted in relation to its frame by a set screw and pawl. The frame bearing the movable jaw has limited motion in relation to the fixed jaw. The frame is connected to the swinging handle by a linkage. The motion of the swinging handle is limited by a second set screw. In operation, this wrench would have approximate adjustment by the set screw in the movable jaw, and the final grip accomplished by the swinging handle through the linkage. |
