Product Description Klein Tools' 1604 Series Messenger and Guy Strand Haven's Grips are designed for use when a light, compact grip is desired, and where cable deformation is not a factor. They are recommended for use with steel strand cables. 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. From the Manufacturer Since 1857, the company operated by Mathias Klein and his descendants to the fifth generation, has grown and developed along with the telecommunications and electrical industries where Klein pliers first found major usages. Today, Klein tools Incorporated represents much more than Klein pliers.

Klein offers a lifetime warranty on material defects and workmanship for the normal life of the product. The Klein 1604-20 grip is designed for use when a light, compact grip is desired and where the conductor damage is not a big factor
