Product information & specifications

The NEW ISC Squirrel FLEX Tether is designed to offer the optimal balance of rigidity and flexibility for SRT Climbing with the 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. 

Minimising 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 karabiner and providing an optimal connection to your rope wrench. The Squirrel FLEX Tether is constructed with contrasting stitching, allowing visibility for easy inspections.

Boasting an impressive 9kN (2023lbf) MBS, the small but mighty hot forged KL100 is the perfect accessory karabiner to provide a direct connection between your chest harness and your SRT system.
