Now available in 11 mm and 13 mm configurations. Built around the all-new CMC CLUTCH™ by Harken Industrial™, the Double CLUTCH Twin Tension Rope System (DCTTRS) Kit delivers best practice, twin-tension hauling and lowering for rescue or training operations.
With the DCTTRS Kit, rescuers can build mechanical advantage systems on two rope systems simultaneously, including a 3:1, 3:1 with change of direction, or complex 5:1. Organized, color-coded, and ready-to-go, this kit minimizes gear sorting and allocation. Rescue teams can shoulder their packs knowing they have everything they need to quickly and efficiently deploy twin tension rope systems (TTRS).
The CLUTCH is smooth, efficient and intuitive, allowing rescuers to haul with ease and lower with control. Innovative features of the CLUTCH make it ideal for TTRS including the ratcheting rotating sheave, Anti-Panic brake, force limiting protection, and integrated becket. When two CLUTCH devices are brought together in the Double CLUTCH Technique, rescuers can maintain nearly equal tension on both lines so that the load, often involving a rescuer, litter, and a victim, is shared across two rope systems, reducing the risk of a single line failure. If a catastrophic event such as single line failure occurs, the Double CLUTCH Technique is preferable to a traditional slack belay because it prevents 100% load transfer on the slack belay line and thereby limits shock and extension in the system.
The DCTTRS Kit includes two G-rated DNA Carabiners that are twisted 90 degrees to align CLUTCH units on the anchor plate. This configuration allows a single operator to manage both CLUTCH handles at the same time for simultaneous twin tension control. While the Double CLUTCH TTRS Kit can be deployed in a variety of ways, rescuers who combine kit components in the Double CLUTCH Technique run a hauling/lowering system that meets current best practices, minimizes failure risk, and offers the potential to reduce personnel requirements.
