Go from Lowering to Raising without Changing Hardware

  • A variable-friction descent control device for rescue systems and rappels
  • Incorporates high efficiency pulley with an integral rope-locking mechanism (ratchet) for a haul system
  • The built-in becket allows cleaner rigging and more efficient pulley systems
  • The MPD allows main line and belay line rigging to be mirror images of one another
  • One device functions as both a lowering brake and as a ratcheting pulley for raising
  • It’s ideal for confined space operations because it converts rapidly to a retrieval line
  • Meets BCCTR Rescue Belay Competency Criteria**

More than nine years of research and development went into our 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, means it can 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
  • Weight: 1.1kg (2 lbs 8oz)


  • Color: Red
  • Rope Size: 13mm
  • MBS at Pulley: 44kN (9,891 lbf)
  • MBS as Descender: 24kN (5,395 lbf)


  • Color: Blue
  • Rope Size: 11mm
  • MBS at Pulley: 44kN (9,891 lbf)
  • MBS as Descender: 21kN (4,721 lbf)
