With just a simple sliding action, the KNIPEX Cobra Quick Set (No. 87 21 250) can adjust its jaw size to provide the perfect gripping action. This addition to the Cobra Water Pump Pliers family combines the features of automatic adjusting pump pliers with the traditional push-button pump pliers. Measuring 10" in length, they feature a 2" gripping capacity and can be used in confined or hard-to-reach areas where access to the nut or bolt is difficult. A built-in shifting mechanism allows the operator to smoothly and easily adjust the tool to the correct capacity when access to the push-button is limited. The tool adjusts easily with one or two hands. Look for the blue push-button that distinguishes this tool from other Cobras in the category.
