The 3M DBI-Sala 3500278 Nano-Lok Edge Twin-Leg Personal Self-Retracting Lifeline is a premium fall protection solution engineered for edge applications where safety cannot be compromised. Designed with a tough galvanized steel cable and Class 2 ANSI rating, this twin-leg SRL provides reliable performance even in demanding environments such as construction sites, steel erection projects, and utility maintenance work. Workers often ask whether this lifeline can be used for foot-level tie-off—yes, it’s specifically rated for such conditions, providing consistent arrest forces and durability at lower anchor points. The heavy-duty steel rebar hooks ensure secure connections to anchorage points, while the compact thermoplastic housing reduces weight without sacrificing impact resistance. This lifeline is ideal for professionals who need 100% tie-off capability when moving between anchors or navigating around sharp edges. Whether used in construction, telecommunications, or energy sectors, this SRL delivers confidence and comfort during long work shifts. Buyers seeking durable fall protection gear often wonder about compatibility with harness systems—this model integrates seamlessly with most 3M DBI-Sala full-body harnesses and other ANSI-compliant harness brands. Backed by the reliability and innovation of 3M, and distributed by Enviro Safety Products—an experienced U.S. supplier of certified PPE—this Nano-Lok Edge Lifeline ensures both compliance and peace of mind for safety managers and field workers nationwide.
