This newest version of the Rope Wrench comes from ISC and is refined with rounded edges, smooth bolts and pins, and the high-end construction you’d expect from ISC. The Singing Tree Rope Wrench is a unique tool for unique climbing arborists.Installed with a stiff tether above a traditional hitch of your choice, the two 90-degree “bends” add just enough friction to the system for a stationary line system to act like a moving or doubled line system.
This imparted drag above a cordage friction hitch opens new and exciting possibilities for climbers. Adding the Rope Wrench gives climbers all the advantages of stationary rope work posi-tioning with the safety and feel of more traditional systems.
The Rope Wrench accommodates only arborist-grade climb-ing lines (11–13 mm) interacting with spliced, heat-resistant, eye-to-eye Prusik cord (8–10 mm). It requires a micropulley/carabiner attachment to the saddle. A 1:1 climbing system in your future? The Rope Wrench is an excellent choice for safe, efficient stationary rope climbing.
WARNING: This product requires experience and possibly train-ing in rope-assisted climbing techniques (specifically SRS as de-scribed above) and tree-related hazard assessment prior to use.
