More is Possible

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.

Features:

  • Single wearable tool for efficient hauling, controlled lowering, smooth personal descent, easy ascending, belaying, and Twin Tension Rope Systems.
  • Delivers up to 38% higher efficiency in hauling and ascending than a cam-style device: reducing changeovers.
  • Moves seamlessly between anchor-based systems and personal use, doing the job of multiple pieces of equipment.
  • Combines the key features of load management devices and personal descenders: reducing equipment training and cost.
  • Instantly transitions between hauling and lowering or ascent and descent without having to transfer the load.
  • Allows main and belay lines to be twin-tensioned in mirrored or nested configurations (Double CLUTCH Technique).
  • Replaces 8 pieces of traditional equipment: pulley, rescue rack, anchor plate, load release strap, prusik cord, and 3 carabiners.
  • 11 mm CLUTCH and CMC G11™ build NFPA G-Rated systems using 11mm rope, saving space and reducing weight.
  • 11 mm CLUTCH is compatible with 10.5 – 11 mm rope and certified to NFPA General Use, ANSI, and EN standards.
  • 13 mm CLUTCH is compatible with 12.5 – 13 mm rope and certified to NFPA General Use and ANSI standards.
  • Patented. Made in the USA.

Components:

  • Stainless steel ratcheting and rotating sheave provides efficient and audible auto-locking progress capture.
  • Rope loading/unloading is secured with an innovative double-latched side plate that is independent of the device‘s attachment point.
  • Anti-Panic brake and force limiting features ensure operational safety and overload protection.
  • Machined aluminum chassis clad with stainless steel wear guards ensures light weight and durability.
  • Integrated becket allows for the direct connection of mechanical advantage components.
  • Control handle has large sweet spot for smooth, progressive lowering and descent control.
  • Included screw can be installed in the side plate to create closed rope systems for rapid deployment.

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.

More refined descents

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

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.
