CMC MPD (Multi-Purpose Device)

Pulley / Rescue Belay / Descent Control
Pat. 7,658,264

The MPD allows you to go from lowering to raising without changing hardware. More than nine years of research and development went into the patented Multi-Purpose Device (MPD), which features major innovations in advanced technical hardware for rope rescue professionals. The MPD’s high-efficiency pulley, with an integral rope-grab mechanism, allows it to be used as a lowering device on the main line and belay line systems and be quickly changed over to a raising system without switching out or replacing hardware. The combination of essential features into a single device simplifies on-scene rigging, expediting the rescue. The revolutionary MPD increases user safety with:

  • Reduced Weight
  • Fewer Components
  • Faster Rigging
  • Quick Changeovers
  • Simplified Training
  • Lower Risk
  • Max load of 272 kg (600 lbs)


The MPD is UL Classified as a Pulley, Descent Control, and Belay device.

  • Variable-friction descent control device for rescue systems and rappels
  • Incorporates a high efficiency pulley with an integral rope-locking mechanism (ratchet) for a haul system
  • Built-in becket allows cleaner rigging and more efficient pulley systems
  • Allows main line and belay line rigging to be mirrored or twin-tensioned
  • Functions as both a lowering brake and as a ratcheting pulley for raising
  • Ideal for confined space operations because it converts rapidly to a retrieval line

The MPD includes a protective Cordura® nylon storage bag and MPD User’s Manual.
