Easier, faster connections for exceptional safety and performance

3M™ DBI-SALA® Nano-Lok™ Self-Retracting Lifeline (SRL) is designed for ease of use and is ideal for direct connection to most safety harnesses. These SRL’s are specifically designed for "hot work" environments such as welding and foundry work. Available in single leg and twin leg models.

Nano-Lok™ is ergonomically designed for ease of use and is ideal for direct connection to most harnesses. The extremely compact and lightweight design is virtually unnoticeable on your back, staying out of the workers way and making it ideal as a lanyard replacement. Whether your application requires single or twin leg configurations, mounting to an overhead anchor or for connection directly to harness, there are dozens of models to choose from to suit almost any application. Nano-Lok™ locks quickly stopping a fall within inches providing more protection at low heights. In addition, tension is always kept on the lifeline, which reduces dragging, snapping and trip falls. Both features are key safety improvements.
