The MPD is a revolutionary tool that allows rescue and rope access professionals to transition from lowering to raising without changing hardware. It can be used as a lowering device on main and belay lines or twin tension systems, and then rapidly converted to a raising system without switching or replacing hardware. This combination of features in a single device reduces weight, simplifies training and on-scene rigging, expedites operations, and increases user safety. MPD Features
