CMC - Double CLUTCH™ Twin Tension Rope System (TTRS) Kit

Built around the versatile CMC CLUTCH™ by Harken™, the Double CLUTCH Twin Tension Rope System (TTRS) Kit delivers best-practice hauling and lowering for demanding technical operations. With two complete rope systems ready to deploy, this premier kit streamlines setup, ensures redundancy, and provides unmatched control for rescuers working in high-stakes environments.

Key Benefits

  • The CLUTCH offers smooth hauling and precise lowering with its rotating ratcheting sheave, Anti-Panic brake, and integrated becket.

  • Mechanical advantage systems (3:1, 5:1, 9:1, and variations) can be assembled quickly on both ropes using the force-limiting CAPTO™

• SQUID™ Rigging Plate Integration

  • Aligns both CLUTCH devices for simultaneous operation.

  • Allows a single operator to manage both devices at once, reducing personnel requirements while improving tension sharing
