Gravity Lab Stiff Tether for Rope Wrench

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"
