ISC APEX With Chipmunk FLEX Tether & Accessory Carabiner

ISC APEX With Chipmunk FLEX Tether & Accessory Carabiner

The ISC APEX With Chipmunk FLEX Tether & Accessory Carabiner is a compact SRT climbing solution designed for efficiency and control. This kit combines the adjustable ISC APEX Rope Wrench with the shorter 9" Chipmunk FLEX Tether and a KL100 Accessory Karabiner, delivering a streamlined and responsive climbing system.

Compact tether for increased reach

The Chipmunk FLEX measures 9 inches, making it 3 inches shorter than the original Squirrel FLEX Tether. This reduced length lowers the overall height of the SRT system, giving climbers more reach above the device and enabling longer arm strides during ascent. The result is improved efficiency and smoother upward movement.

Rigid construction with controlled flex

Constructed from high quality kernmantle rope with an advanced polymer over-mould, the Chipmunk FLEX provides a super-rigid tether with just the right amount of flexibility. Sewn eyes ensure a snug karabiner fit, maintaining stiffness and minimising unwanted slack within the system.

Complete APEX climbing kit

The KT305A1 kit includes the ISC APEX Wrench, Chipmunk FLEX Tether and KL100 Accessory Karabiner. The tether features a central connection point for attachment to a chest harness. Designed for use on 11–13 mm rope, the system delivers consistent performance for SRT climbing applications.
