Absolutely revolutionary device designed by Kirk Mauthner.

The MPD™ can be used as a lowering device, a self ratcheting high efficiency pulley, or even a rescue belay device.

Instantly change from a lower to a raise with no change of equipment. You can switch the mainline to a belay line, and visa versa, or create mirror image systems.

There is a becket hole to streamline rigging.

In belay mode, the MPD™passes the ultra stringent BCCTR Belay Competency Drop Test.

For use with 12.5mm ropes.

Meets NFPA 1983 (G) guidelines for both Accessory Devices and Desent Control Devices.
