CMC™ and Harken Industrial™ Announce the CLUTCH™ Multipurpose Tool

Santa Barbara, CA—The CMC and Harken Industrial CLUTCH is intuitively designed for ease of operation and optimal descent control. This multipurpose 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.

  • Rope loading/unloading is secured with an innovative double-latched side plate design 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 lightweight durability.
  • Integrated becket allows for direct connection of mechanical advantage systems.
