ISC Apex Rope Wrench Kit with Squirrel Flex Tether
The ISC Squirrel Flex 12" Tether is designed to offer the optimal balance of rigidity and flexibility for SRT Climbing with the Apex Rope Wrench. The Squirrel Flex is made from a high-quality kernmantle rope, over-moulded with an advanced Polymer, selected to create a rigid tether that allows just the right amount of flex and an ultra-premium finish.
Minimizing unwanted slack in a climbing system is always a high priority, so we designed the sewn eyes to offer a snug fit, firmly holding the carabiner and providing an optimal connection to your ISC Apex rope wrench. The Squirrel Flex Tether is constructed with contrasting stitching, allowing visibility for easy inspections. Boasting an impressive 9kN (2023 lbs) MBS, the small but mighty hot forged KL100 is the perfect accessory carabiner to provide a direct connection between your chest harness and your SRT system.
