Harken CMC Clutch

The 11mm CMC Clutch by Harken Industrial is a multi-purpose device for hauling, controlled lowering, smooth personal descent, easy ascending and reliable progress capture - it is the latest evolution in rescue and rope access hardware that enables the technical rope professional to do more with less.
Suited to a multitude of rigging operations, the CLUTCH delivers efficient operation, ease of use, and optimal control. It moves seamlessly between anchor-based systems and personal use.  
  • The Clutch is a single device that offers efficient hauling, controlled lowering, smooth personal descent, easy ascending, belaying, and Dual Capability Twin Tension Rope Systems.
  • The Clutch offers a 38% increase in efficiency when hauling and ascending compared to a cam-style device.
  • It allows a seamless transition between anchor-based systems and personal use thus doing the job of multiple pieces of equipment.
  • Combines the key features of load management devices and personal descenders into one device helping to minimise training burdens and cost.
  • Very fast transitions between hauling and lowering or ascent and descent without having to transfer the load.
  • The body design allow two devices to be run side by side so allowing main and belay lines to be twin-tensioned in mirrored or nested configurations. 
  • Replaces up to 8 pieces of traditional equipment: pulley, anchor plate, rescue rack, load release strap, prusik cord, and 3 carabiners.
