The Rollgliss™ R550 offers the choice of controlled descent rescue, evacuation or the versatility of assisted rescue with lifting capabilities. It features 3/8 in. (9.5 mm) super static kernmantle rope, and is configured with connecting hardware at each end of the lifeline to operate in both directions. During assisted rescue scenarios, a fallen worker can be attached to the R550 device, raised to a point that allows their fall arrest device to be removed, then lowered to the ground safely.
