The PWZ3 Adjustable Pipe Pliers Wrench from Snap-on offers a 3-1/2" jaw capacity and inward-angled teeth (with fine teeth at the back of the jaws, larger teeth at the front), resulting in a stronger, more secure grip. The multi-purpose wrench has a quick-adjust grip and can easily be locked into the desired position with the adjusting screw. For added safety, the inner handle has a built-in mechanism to protect against pinching.
