Unmatched preparedness and value

The CLUTCH combines the attributes of more expensive multipurpose devices with those of less sophisticated wearable personal descenders. Rescue teams can carry less equipment while assuring they’re prepared for even the most technical rescues.

More refined descents

The patented mechanical geometry inside CLUTCH and its ergonomic handle, combine for better control across the load range in descent.

Efficiency that improves performance

CLUTCH features a faceted ratcheting sheave of stainless steel that provides secure rope holding and audible progress capture. It also proves to be uncommonly efficient on ascent or haul.

Designed to be intuitive—and safe

CLUTCH is designed for efficient operation, ease of use and optimal control. Its innovative double-latched side plate is independent of the device‘s attachment point and resists inadvertent opening. Rescuers and access professionals can change rope without disconnecting.

The versatile CMC™ CLUTCH™ by Harken Industrial™ is a single wearable tool suited for efficient hauling, controlled lowering, smooth personal descent, easy ascending, and reliable progress capture. Not only does it replace the hardware used in a traditional raise/lower system for rescue operations, it also serves as a personal descender with the most efficient ascending capability of any product in its class. The CLUTCH enables more rope operations with one tool than anything we’ve ever evaluated. The CLUTCH is the result of the design and product engineering collaboration by two experts 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.
