| The movable jaw can be shifted in relation to the sliding bar by depressing the spring. The lever handle moves the sliding bar to fully tighten the grasp of the jaws. T movable cam can "lock" an adjustment by keeping the sliding bar from moving. The sides of the jaws have grooves to hold auxiliary pipe jaws, axle-nut grasping jaws, and a jaw and handle combination for a tap wrench. |
