    ISC Apex Rope Wrench Kit with Chipmunk Flex Tether

    $224.95
    In stock

    The 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 ISC Apex Rope Wrench 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.

    The Chipmunk FLEX measures 9", which is 3" shorter than the original Squirrel FLEX Tether.  A compact climbing system allows climbers more reach-space above the system, therefore enabling longer arm strides and greater efficiency during ascent. Just like the Squirrel, the Chipmunk is constructed from high quality, durable rope with an advanced Polymer over-mould, to create a super-rigid tether, with just the right amount of flex!

    • This kit includes an Apex Wrench, Chipmunk Flex Tether and accessory carabiner

    Compact set up

    Definitely like the compactness of the chipmunk tether with the apex it goes nice with the reflex, the system is not long like utilizing a regular tether and rope wrench or the zigzag with chicane. Best thing Is that you can easily adjust the friction on the apex depending on the rope diameter you are running
