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.
