Dedicated to the pursuit of keeping workers safe at heights

The 3M™ DBI-SALA® Nano-Lok™ Personal Self-Retracting Lifeline (with anchor hook) 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.

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 3M™ DBI-SALA® Nano-Lok™ SRL (with anchor hook) achieves 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.
