The 3M DBI-SALA® Nano-Lok Edge Self Retracting Lifeline is a purpose-built fall protection device certified to ANSI Class 2 standards for foot-level tie-off and leading edge applications — environments where conventional overhead-anchorage SRLs are not appropriate or safe to use. Leading edge applications present unique fall protection challenges because the lifeline may contact the sharp edge of a structure during a fall, and the anchorage point is often at or below the worker's feet rather than overhead. The Nano-Lok Edge is specifically engineered and tested to address these conditions, making it one of the most important distinctions in fall protection product selection for construction and structural work.
The ergonomic design of the Nano-Lok Edge prioritizes ease of use in active work environments, with a compact and lightweight form factor that reduces fatigue and improves maneuverability. The unit is designed for direct connection to most full body harnesses, simplifying the setup process and reducing the need for additional hardware or adapters. This direct connection capability makes the Nano-Lok Edge a practical and efficient choice for workers who need to don and connect their fall protection quickly at the start of a shift or when transitioning between work areas.
The quick activating speed sensing brake system arrests falls rapidly and within a short distance, which is critical in foot-level and leading edge scenarios where fall clearance below the work surface is limited. The Nano-Lok Edge is well suited for steel erection, concrete formwork, decking, roofing, and any other construction application where the anchorage point cannot be positioned overhead and leading edge exposure is present.

Note: This SRL is specifically designed and rated for ANSI Class 2 leading edge and foot-level anchorage applications. It must not be substituted with a standard Class 1 SRL in these scenarios. Always verify anchorage compatibility, fall clearance, harness compatibility, and ANSI classification requirements prior to use. Follow all 3M DBI-SALA® instructions for use and inspection requirements.
