The 3M™ DBI-SALA® Nano-Lok™ Edge Self-Retracting Lifeline (SRL) 3500218 is specifically engineered for foot-level tie-off and leading edge applications, making it ideal for construction and industrial work environments. Featuring a compact and ergonomic design, this 8 ft (2.4 m) galvanized cable lifeline provides enhanced mobility and safety, while its quick-activating speed-sensing brake system ensures rapid fall arrest within inches, offering increased protection at low fall clearance heights.

Designed for direct attachment to most harnesses, this SRL integrates a high-capacity external energy absorber, which helps mitigate fall forces, while the built-in impact indicator simplifies inspection for safety compliance. The rugged thermoplastic housing ensures durability in harsh environments, while RFID-equipped technology allows for seamless inventory management and tracking.

Whether used as a lanyard replacement, mounted to an overhead anchor, or configured in single or twin-leg setups, the 3M™ DBI-SALA® Nano-Lok™ Edge SRL offers versatility, safety, and reliability in high-risk work conditions.
