The versatile CLUTCH 11mm by Harken Safety & Rescue 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 Safety & Rescue, a manufacturing company with roots in high-performance sailing.
