10" Cobra Water Pump Pliers
The Knipex 87 01 250 is a 10-inch tongue-and-groove plier designed for gripping and turning pipes, fittings and fasteners. Its push-button adjustment offers 25 jaw positions so the tool adapts quickly to different workpiece sizes.
Box-joint design with double guide
The box-joint construction and double guide keep the jaws aligned under load, reducing play and preventing the joint from shifting. A pinch guard protects fingers during fast adjustments, while the self-locking action holds the workpiece without constant squeezing force.
2-inch maximum jaw opening and 61 HRC teeth
Hardened gripping surfaces at approximately 61 HRC bite securely on round and flat stock up to 2 inches wide. The V-shaped serrated jaws concentrate force for a firm hold, but the tool is not insulated, non-sparking or tether-ready, limiting its use in live-electrical or hazardous-environment work.
