ISC Singing Tree Rope Wrench

Category: Tag:


Over the past four years, the ISC Singing Tree Rope Wrench (STRW) has become a well established, popular tool within the Production Climbing industry. Use of the Rope Wrench in competitions has been limited, as the STRW had not been widely recognised by climbing competition organisations/committees…until now!

The ISC Singing Tree Rope Wrench kit is now approved for use in ISA Competitions. Please note that ONLY the full ISC kit (STRW, ISC Rope Wrench Pulley and ISC Tether), have been tested and accepted by the ISA.

Set includes Rope Wrench, Rope Wrench Pulley, and Tether.
