The Klein Tools 1671-10 Parallel Jaw Grip works with a wide range of cable types and sizes. The longer, knurled jaws provide a firm hold on the cable, reducing the possibility of slippage and deformation. All Klein grips are manufactured from custom drop-forged steel that is machined and heat treated for excellent durability. Each grip is individually hand inspected and actuated for proper function. Grips are also rigorously tested and pulled to rated load to ensure the highest quality and reliability.
