To help improve fall protection, the 3M™ DBI-SALA® Nano-Lok™ Extended Length Self-Retracting Lifelines are going to considerable lengths. The Nano-Lok™ SRL family, available in 9 ft., 11 ft., 15 ft., and 20 ft. lengths, combines fall protection with ease of use and comfort for even more applications.

The Nano-Lok™ Extended Length Self-Retracting Lifeline combines a lightweight design with the durability and functionality of industrial-strength materials. The primary focus is on enhancing the comfort and safety of the worker with an easy-to-use system ideal for direct connection to most harnesses. Because of its exceptionally small and lightweight design, it is virtually unnoticeable on your back, staying out of the worker's way and making it ideal as a lanyard replacement.

Whether your application calls for single or twin-leg configurations, mounting to an overhead anchor, or connecting directly to a harness, there are a variety of fall protection models to accommodate almost any application.

The smart activation brake mechanism of the Nano-Lok™ locks quickly — achieving fall clearance as low as 4 feet while preventing a fall within inches and giving better protection at low heights. In addition, the lifeline's constant tension prevents slack which can cause dragging, snapping, and trip falls. These features are significant advancements in terms of safety and offer the user increased protection while on the job.

Product Highlights
