Notify me when this product is available:

The CMC Clutch is the latest evolution in rope access and rescue hardware.

Introducing the all-new CLUTCH, the latest evolution in rescue and rope access hardware that enables the technical rope professional to do more with less. This multi-purpose device was designed and engineered in collaboration by two companies with a collective 90 year history in rope management under heavy loads: CMC, a company with roots in rescue and rope access, and Harken Industrial, a manufacturing company with roots in high performance sailing.

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, offering unmatched versatility for the rope technician. With the CLUTCH, more is possible.
