Screamer Zipper - 22"
Shock absorbing sling designed to reduce peak loads in any climbing system.
The "ZIPPER" can effectively reduce peak loads by 6-8kN in any climbing system. Screamers and Zippers have proven to be very successful in reducing loads to any anchor when it is stressed in excess of the activation force of the Screamer device.
Screamers are single-use energy absorbing devices which have been used in rock and ice climbing on marginal anchors for decades, ”I started using them in tree work 10 years ago,” says veteran Arborist Dave Stice. ”They are an important item to have in the toolbox for extreme situations.”
Screamers can be used in your rigging system to reduce peak forces by up to 600 lb. They are great for extremely tight drop zones, situations where you don't have room to let the rope run, or for dead and decaying trees. If you are working with new groundsmen, using one of these in the system can avoiding the whiplash effect if the rope is not let run properly.
