The Rollgliss™ R520 is a state of the art, easy-to-use fully automatic controlled descent device with a dual braking system that sets new standards in performance, rescue and safety. Unlike friction based descenders, it provides controlled descent self-rescue regardless of the user's weight for the evacuation of multiple personnel, or the versatility of assisted rescue. The Rollgliss™ R520 can be used from heights of up to 500 ft (152 m) from elevated work platforms, towers, cranes, building or other heights. Its compact size allows the unit to be attached to the rescue box of a work platform basket, crane housing or other suitable anchorage. Each kit is available in a variety of lengths, configured with connecting hardware at each end of the lifeline and is pre-rigged and ready for use in the event of an emergency. The descender's configuration allows the device to operate in both directions - one end of the lifeline descends as the other ascends, readying the system for another rescue.
