The Double CLUTCH Twin Tension Rope System (TTRS) Kit is a complete, best-practice hauling and lowering solution built around the versatile CMC CLUTCH™ by Harken™. Designed for technical rescue operations, this advanced kit allows rescuers to deploy two independent rope systems at separate anchors or in a side-by-side configuration for true twin-tension operation. Organized, color-coded, and ready for rapid deployment, the kit minimizes gear sorting while providing the equipment necessary for efficient hauling, lowering, and load management.
The system utilizes two CLUTCH devices, two CAPTO™ progress-capture pulleys, and the innovative SQUID™ Rig Plate to create mechanical advantage systems including 3:1, 3:1 with change of direction, 5:1, and 9:1 configurations. The included SWIVO™ pulleys streamline transitions between hauling and lowering while improving overall system efficiency. Twin-tension systems help distribute loads between two ropes, reducing the risk associated with single-line failures while limiting shock loading and system extension should a failure occur.
