ISC Rope Wrench Double Tether (Twin Tether)

Description ISC Rope Wrench Double Tether – Twin Tether SRT Rope Wrench The ISC Rope Wrench Double Tether (Twin Tether) is the dual-tether version of the Singing Tree / ISC Rope Wrench, designed to promote symmetry on the lower sheave and improve system balance during SRT (Single Rope Technique) ascent and descent. It is the preferred configuration for arborists seeking maximum performance and rope alignment in their SRT setup. Key Features By using two tethers rather than one, the Double Tether distributes load more evenly across the lower pulley and maintains the rope wrench in an optimal orientation throughout the full range of climbing movements — particularly during ascent phases where alignment is critical. It pairs with the PHLOTICH or Hitch Climber pulley and a friction lanyard to create a complete, high-performance SRT ascent and descent system. Available in Red and Purple. CE EN 12278 certified. Manufactured by ISC Wales (by Singing Tree).
