3M 7100207461 R550 Controlled Descent Device 620 Lb

Product Description

The 3M 7100207461 is the Rollgliss R550 Controlled Descent Positioning Device, a fully automatic rescue and evacuation tool designed for work-at-height professionals in industrial, utility, and transportation environments. Built around a 3/8-inch super static kernmantle lifeline with aluminum hardware at each end, the R550 supports single-user descents from heights up to 1,640 feet and two-user loads totaling 620 pounds from heights up to 575 feet. The device operates in both directions, making it suitable for controlled descent evacuation as well as assisted rescue with lifting capability. Licensed riggers, safety technicians, and rescue teams install and operate this device on qualified anchor systems.

The R550 is recommended for transportation, utility, and general industrial applications where workers may need rapid evacuation or rescue from elevation. In assisted rescue scenarios, a fallen worker can be connected to the R550, raised enough to clear their fall arrest equipment, and then lowered safely to the ground. The lifeline is configured with connecting hardware at both ends to allow bidirectional operation without reconfiguration. This versatility makes it a practical choice for facilities that require a single device to handle both self-rescue and attended rescue operations.

Key Features

• 620 lb maximum weight capacity supports two-user rescue loads
• 3/8-inch super static kernmantle rope construction for high-strength, low-stretch performance
• Aluminum hardware at each end of the lifeline enables bidirectional operation
• Fully automatic controlled descent — no manual braking required during lowering
• Lifting capability supports assisted rescue of a fallen worker before lowering
• Meets ANSI/ASSP Z359.9-2021 and CSA Z259.2.3-12 standards

Compatibility

The 3M 7100207461 R550 is designed for use in transportation, utility, and general industrial applications. Consult the manufacturer documentation to confirm anchor system requirements and compatibility with your site-specific rescue plan before deployment.

Installation Notes

Installation, inspection, and operation must be performed by a qualified person trained in rescue and fall protection systems per applicable ANSI/ASSP Z359 and CSA Z259 standards. Verify that the anchor point meets or exceeds the rated load capacity of the device before use. Inspect the kernmantle rope and hardware for damage, kinks, or wear prior to every deployment. Do not modify, cut, or field-repair any component of the lifeline or hardware.
