  • Smarter retraction and smoother reaction

    Applying science to the safety of motion makes for a more intelligent approach to protection at heights. We studied how you work, move and interact with self-retracting lifelines to create 3M™ DBI-SALA® Smart Lock Self-Retracting Lifelines. See what we learned, and how we harnessed the science of safety to create fewer unintentional lockups. Make your work at heights easier and more productive with smarter retraction and smoother reaction.


Motion profile testing on construction worker

3M's Science of safety at work.

Unlock your productivity. From reducing unintentional lockups* to simplifying inspections, every detail of the new 3M™ DBI-SALA® Smart Lock Self-Retracting Lifelines is designed to help increase your productivity and convenience.

How did we create an SRL that reduces unintentional lockups? Using advanced motion capture technology, 3M studied the way users work, move and interact with SRLs on a typical job site. This data helped us engineer an arrest mechanism designed to better accommodate your natural work motions—resulting in fewer unintentional lockups.*


  • Horizontal (Leading Edge) 29% Fewer sudden stops*.

    Significant testing was completed to make this product work while reducing the  unintentional lockups. Compared to our existing devices, the new Smart Lock SRL locked up to 29% less when tested against 422 work motion profiles. **

  • Vertical (Overhead) As low as 4 ft (1.2 m) fall clearance.
