3M™ DBI-SALA® Rollgliss™ R550 Rescue and Descent Device Kit
The 3M™ DBI-SALA® Rollgliss™ R550 is a fully automatic controlled-descent and assisted-rescue system designed for emergency evacuation and rescue from elevated work areas. Its bidirectional design, integrated rescue lifting capability, and 3/8 in (9.5 mm) kernmantle rope allow trained rescue teams to perform controlled descents, evacuations, and assisted rescues with one versatile system.
Why It's Used
Rescuing a suspended or stranded worker may require more than simply lowering them to the ground. The Rollgliss™ R550 allows a trained rescuer to raise a fallen worker enough to disengage their existing fall-arrest system before transitioning them into a controlled descent.
Its bidirectional design also allows one end of the lifeline to ascend as the other descends, supporting efficient evacuation and rescue operations from elevated structures.
Key Features
- Fully automatic controlled-descent system
- Designed for rescue, evacuation, and assisted-rescue applications
- Integrated rescue lifting capability
- Bidirectional operation
- Dual-brake design
- 3/8 in (9.5 mm) super-static kernmantle rope
- Connecting hardware at both ends of the lifeline
- High-strength, corrosion-resistant construction
- Aluminum and stainless-steel device construction
- Designed for one- or two-person rescue applications within specified limits

- No external power source required for controlled descent
Compatibility
The Rollgliss™ R550 is designed for integration into a site-specific fall-protection and rescue plan using approved anchorage, compatible full-body harnesses, connectors, and other equipment appropriate for the rescue scenario.
The rescue model's integrated lifting capability allows a trained rescuer to raise a suspended worker sufficiently to disengage the worker's fall-arrest system before beginning controlled descent.
Always confirm the specific R550 model, rope length, anchorage requirements, user capacity, and compatible equipment before use.
