The ISC Singing Tree Rope Wrench has become a well established, popular tool within the production climbing industry and in tree cimbing competitions.
The Rope Wrench provides an 'S' bend in the rope above the hitch cord. This effectively provides a contained double rope system, on a single rope, which shares the user's weight between the Wrench and the hitch. This allows the operation of the hitch, without the need for a double-rope system. The Rope Wrench allows easy horizontally movement, with greatly reduced friction on re-directs (compared with DdRT).
