The first ISC Rope Wrench was launched in 2013, unlocking the potential of Stationary Rope Climbing and quickly establishing itself as the most popular SRT climbing system worldwide.  The APEX builds on the performance characteristics of the original Rope Wrench by offering additional functionality and convenience, together with unrivalled ISC build quality.

The NEW ISC APEX is fitted with an adjustable cam, allowing the user to select from multiple clearly identifiable friction settings, in accordance with rope type and diameter.  The spring-loaded cam can be adjusted in under 5 seconds- simply depress the spring-loaded button, swing the side plate open and then pull the spring-loaded cam outwards a short way.  Rotate the cam to select the new setting, release the cam and close the device!  No tools needed and no drop-able parts!

 The NEW ISC APEX is fitted with a swing-open side frame which allows for quick and easy mid-line attachment, even when wearing gloves! The push-button, swing-open side frame has a double-lock closure system for added security and an audible ‘click’ to confirm closure. 

The ISC APEX also allows the user to change the tether without having to alter the friction setting.

Squirrel FLEX Tether, with Accessory Karabiner

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.
