D33 Micron Descender Self Evacuation system

The MICRON descender allows a person to make a controlled descent from high level with unique, patented braking system with secondary panic lock.

It gives double action safety and fine control using pre-loaded, high strength, heat resistant Aramid cord.

Potential use by anyone who works at height, but perfect for the onshore and offshore wind industry.

Its compact small size (equivalent to 10 mm karabiner) provides full size functionality, is lightweight and easy to carry on the harness as part of the full evacuation system.

The MICRON descender is only available in the MicroPack Evacuation System (D33***). This kit offers the functionality of a traditional system at the fraction of the size. Small and light, the system can be carried at all times and can be used for descent or to lower or raise a casualty.

Standard lengths available: 15m, 50m, 120m. Please contact us for bespoke lengths.
