The Gravity Lab Stiff Tether is designed for use with the ZK-2 Singing Tree Rope Wrench.
This tether is CNC machine sewn from 8mm Teufelberger Ocean Polyester cordage and is covered with 2 layers of premium quality adhesive lined heat shrink.
The rubber bump-stop helps prevent the wrench from staying in neutral position after ascent, reducing sit-back and setting the wrench more reliably.
Available in a choice of 2 finished lengths:
- 30cm / 12"
- 25cm / 10"
