The 3M DBI-SALA® Nano-Lok™ Extended Length Self-Retracting Lifeline with galvanized steel lifeline is designed to help improve fall protection while maintaining worker mobility in demanding environments. Its impact-resistant thermoplastic housing is built to withstand harsh worksites, while the speed-sensing brake system limits required fall clearance to as low as 6 ft (2 m). A swiveling anchorage loop helps reduce lifeline twisting for smooth operation, and an integrated impact indicator provides a clear visual alert if the unit has been involved in a fall. Designed for overhead anchorage use, this extended-length SRL supports reliable performance for work at height.
