ISC Apex Rope Wrench Ascender

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.
