Induction-hardened gripping teeth and push-button adjustment allow Cobra Pliers to safely and securely latch onto pipes, nuts and other hard-to-grasp objects. Just position the upper jaw to a workpiece, depress the patented push button and slide the lower jaw into place underneath. Adjustable among several positions, these 7 in., 10 in. and 12 in. water pump pliers self-lock onto hex nuts and pipes without fear of crushing fingers thanks to an anti-pinching guard that prevents the handles from clamping on top of each other.
