This simple, easy to use ROTOR rescue and evacuation descender design includes a low profile body with no external moving parts that have the potential to snag and interrupt the descent. Internal mechanism is completely sealed against the ingress of water or other contaminants.

The ROTOR rescue and evacuation descender features attachment load point indicator that shows if device has been used.

Lifts in either direction via detachable handle. Ratchet locking mechanism holds the load if the handle is released. Locking mechanism is engaged by simple push button, which is recessed to protect against accidental operation. ‘Free running’ position can be engaged for evacuation use.

Automatically controls descent speed to between 0.7 m/s and 1.7 m/s, depending on load, without the need for manual operation.
