The KNIPEX Cobra® XL and XXL offer the performance and comfort of a water pump pliers with less weight and a greater gripping capacity than comparable pipe wrenches. The Cobra® XL can grip a 2" pipe fitting, for example, and weighs 50% less than a 2" pipe wrench, which has a much lower gripping capacity. With its handy 400 mm length, the Cobra® XL also fits in the plumber's toolbox.
