The Nano-Lok™ edge twin-leg tie-back quick-connect SRL is engineered for safe and convenient foot-level tie-off in situations where no other viable anchor points are present. The 8 ft (2.4 m) galvanized steel lifeline resists abrasion, and the twin legs allow for movement from point to point with 3 ft (1 m) heavy-duty tie-back webbing and hooks at the ends. The speed-sensing brake system brings a fall to a halt within inches and disperses the arrest forces to protect the worker, and the swiveling anchorage loop will prevent tangles in the line.
