Rescue MPD, Pulley Belay Descender - 11 mm, Grey, CMC


An innovation in rope rescue! 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

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 mirror images of one another in a DCTTRS.

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.

Meets BCCTR Rescue Belay Competency Criteria**.

The MPD comes with a padded Cordura nylon storage bag and User's Manual.


11 mm model is designed for and tested with 11 mm rope. 11 mm model UL rated 'T' Technical Use for descent control.

** The British Columbia Council of Technical Rescue (BCCTR) Belay Competency Drop Test specifies a 1-meter drop onto 3 meters of kernmantle rescue rope with less than 1 meter of additional travel and less than 15 kN peak force.

For a Technical Use device, a 200-kg load and an 11-mm rope are used.
