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.

Features

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.

Features a faceted ratcheting sheave of stainless steel.

Provides a secure rope holding and audible progress capture.

Combines the attributes of more expensive multipurpose devices with those of less sophisticated wearable personal descenders.

As a result, rescue teams can carry less equipment whilst assuring they're prepared for technical rescues.

The double latched side-plate is independant of the devices attachment point.

Allows rescuers and access professionals to change the rope without disconnecting.

Patented mechanical geometry inside the device and an ergonomic handle.

Combine to offer better control across the load range in descent.
