The 3M™ DBI-SALA® Ultra-Lok™ Self Retracting Lifeline, 3501104, is a self retracting lifeline (SRL) designed with an anti-ratcheting self-adjusting disk brake system that stops a fall within inches to keep you safe when you're working at heights. Equipped with 50 ft (15.2 m) of 3/16 in (5 mm) galvanized steel cable and lightweight thermoplastic housing, this SRL also includes corrosion-resistant hardware—a swiveling anchorage point and a swiveling snap hook with impact indicator.

Ultra-Lok™ self retracting lifelines (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.
