The 3M™ DBI-SALA® Rollgliss™ R550 Rescue and Descent Device offers the choice of controlled descent rescue, evacuation or the versatility of assisted rescue with lifting capabilities. This state of the art, fully automatic controlled descent device can be used for rescue and evacuation from heights up to 1,640 ft (500 m) for one user 310 lbs (141 kg) or 575 ft (175 m) for two users totaling 620 lbs (282 kg). 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.
