ISC Singing Tree Rope Wrench

Designed specifically for SRT (Single Rope Technique) climbing, the Singing Tree Rope Wrench offers the advantages of stationary rope work positioning with the safety and feel of more traditional systems. Install the Rope Wrench along with a stiff tether above a traditional hitch of your choice. The Rope Wrench helps to create drag above the rope-tied friction hitch to reduce resistance, making the system comparable to the doubled rope technique. Accommodates only arborist-grade climbing ropes (11 to 13 mm) interacting with spliced, heat-resistant, eye-to-eye Prusik cord (8 to 10 mm). Requires a micropulley/carabiner attachment to the saddle.
