The 3M™ DBI-SALA® Nano-Lok™ Edge Self-Retracting Lifeline is engineered for foot-level tie-off and leading edge applications commonly encountered in construction and industrial environments. Designed to meet ANSI Class 2 requirements, this compact SRL mounts directly to most full body harnesses for improved mobility and reduced bulk. With a galvanized cable lifeline and rapid locking mechanism, it delivers dependable fall protection where sharp edges and lower anchorage points are present.
