ISC Squirrel Tether with Pulley

ISC Squirrel Tether with Pulley

The Squirrel Tether is the only metal tether engineered by ISC for use with the Rope Wrench. Machined from lightweight aluminium, it minimizes twist and flex for smoother, low-friction ascents and efficient lateral movements within the canopy.

An integrated pulley and stopper bollard keep the Rope Wrench correctly positioned while protecting the user’s hand. Four SRS chest-harness attachment points allow custom mounting, and a secondary aperture supports rescue setups. Compatible with 11–13 mm Rope Wrench (RP280), this replacement tether carries Registered Design No. 6108494.
