The Knipex Cobra XL, No. 87 01 400, and XXL, No. 87 01 560 Pipe Wrench and Water Pump Pliers, have fast push-button adjustment, to avoid unintentional joint slippage. The XL pliers can grip a 2" pipe fitting and weigh 50 percent less than a 2" pipe wrench, which has a much lower gripping capacity. The XXL pliers have the weight of a 2" pipe wrench but offers a back-up gripping capacity up to 4 1/2".
