The ISC Singing Tree Rope Wrench has become a well-established, popular tool within the production climbing industry and in tree climbing 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. The Rope Wrench 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 horizontal movement, with greatly reduced friction on re-directs (compared with DdRT).
The Rope Wrench system has been third-party tested and certified by a Notified Body, to PPE ‘Regulation 2016/425′, allowing users to climb in compliance with the latest European best practice regulations.
IMPORTANT, PLEASE NOTE:
The PPE Regulations Certification applies to kits when used in their entirety, in accordance with the User Instruction Manual.
