Singing Tree Rope Wrench Pulley

The Singing Tree rope wrench pulley is made for climbers running the Singing Tree Rope Wrench on a stationary rope. It helps tend slack through the hitch and wrench so the system moves more smoothly on ascent and when working out on limbs.

How it fits the wrench system

The Rope Wrench adds friction above a climbing hitch so a hitch can work on a single, stationary rope. The hitch still needs tending, and a pulley below it lets you pull slack through with one hand as you move.

A pulley made for the same system is designed to work with the wrench and tether rather than fighting them. That keeps the setup compact and helps the wrench follow the hitch on ascent instead of hanging up.

Many climbers set up their wrench system once and leave it, so a matched pulley means fewer variables to manage. When it comes time to replace a part, staying with parts made for the system keeps the behavior you are used to. If you are new to the wrench, learn the system with an experienced climber before changing any part of it.

Setup and inspection

Follow Singing Tree's instructions for how the pulley, hitch, tether and wrench go together, and test the full system close to the ground before you climb. Small changes in hitch length or tether length change how the system behaves.

Inspect the pulley for cracks, grooves, deformation and a stiff sheave before each climb. SRS systems are life support, so use them within the maker's instructions and ANSI Z133 practice, and get trained first. See more options in micro pulleys.
