Description: |
| The adjusting collar has internal interrupted threads allowing for screw and quick adjustment, and a stop to prevent full rotation. The interior of the movable jaw has a spring-loaded detent which engages one of a series of notches in the edge of the adjusting collar. This combination provides quick & screw adjustment with the detent to hold the adjustment against accidental movement. |
