With the Knipex 00 19 55 S7 three-piece pliers wrench set, you can install and tighten delicate or chrome-plated fittings without leaving surface scratches. The three pliers wrenches in lengths of 150 mm (86 03 150), 250 mm (86 03 250), and 300 mm (86 03 300) replace a full set of metric and imperial open-end wrenches up to a jaw capacity of 68 mm (2 1/2 inches). Thanks to the smooth push-button adjustment, the parallel jaws grip bolts with zero backlash. a lever transmission greater than 10:1 delivers powerful clamping force while enabling fast ratcheting action. The set stays organized in the included hard-wearing polyester tool roll.
