The MPD™ is an Innovation in Rope Rescue that allows you to go from lowering to raising without changing hardware. More than nine years of research and development between CMC and Rock Exotica 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
The MPD is UL Classified as a pulley, descent control device 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 comes complete with a padded Cordura nylon storage bag and User’s Manual.

Not recommended as a Back-Up device for rope access.
