this versatile CMC CLUTCH 13 mm 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, but 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 and meets NFPA regulations suitable for fire/rescue operations with larger ropes

key features

  • 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
  • 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
