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.
