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, and Lower Risk. The MPD is UL Classified as a pulley, descent control device and belay device.
