No more time-consuming test-adjusting to achieve the correct size. With the Knipex Cobra XXL water pump pliers, you can simply position the upper jaw to the workpiece, push the button, and close the lower jaw. The 16-inch Cobra XXL (model 87 01 560) offers the power and comfort of water pump pliers while being lighter in weight and having a greater gripping capacity than comparable pipe wrenches. It can grip a 4-1/2-inch pipe coupling and weighs as much as 2-inch pipe wrenches, which have a much lower gripping capacity. And its 22-inch size makes it the biggest pliers around.
