The 3M™ DBI-SALA® Ultra-Lok™ Self-Retracting Lifeline (SRL) is durable, lightweight, and engineered for safety, efficiency, and reliability. It is available with synthetic rope, stainless steel, or galvanized steel cable lifeline material, and an aluminum or thermoplastic housing. The 3M™ DBI-SALA® Ultra-Lok™ Self-Retracting Lifeline (SRL) RSQ™ design is a dual-mode SRL for fall arrest and integrated rescue systems. 3M™ DBI-SALA® Ultra-Lok™ Self-Retracting Lifelines are available in SRL, Retrieval SRL, and RSQ™ configurations.

Ultra Lok self retracting lifelines (SRL’s) are rugged, yet extremely lightweight and superbly engineered devices you can count on for safety, efficiency and comfort. Stainless steel components, an anti ratcheting brake system and a semi sealed design provide the user with a system built to last. Our SRLs are backed by decades of proven field service for absolute confidence, safety and reliability. An SRL’s lifeline will extend as the user moves away, and retract automatically enabling the user to move about within a recommended working area at normal speeds. Should a fall occur, a speed sensing brake system will activate stopping the fall and reducing the forces imposed on the user to safe levels.
