Models MIO-D and MIO-R are unique Rope Descenders with two built in mechanisms: Automatic Overspeed Control and a Lever Break Control. Automatic Overspeed Control: The built-in mechanism ensures complete stop in the event the speed goes over the allowed parameters without operator's involvement. Descent control: Lever Break Control Mechanism permits the operator to vary the speed and brake at any time by moving the lever. The user is able to descent from a full "stop" to a full "go".

Model MIO-D2 and MIO-R2 are compact and lightweight Rope Descenders with built in Lever Break Control Mechanism which allows the operator to vary the speed and stop at any time without being concerned with the free end of the rope not being tied up. Moving the lever allows the user to initiate descent from a full "stop" to a full "go".

Rack Type Descenders:
The rack and bar systems allow the user to control rate of descent by varying the amount of friction by changing spacing between bars and changing the amount of bars being used. Model RR-3 is equipped with a swivel eye for proper alignment when used with working, rescue or climbing harnesses.
