The 3M Protecta Self-Retracting Lifeline (SRL) extends and retracts with the user as they perform their work task. Should a fall occur, a speed sensing brake system activates, stopping the fall and reducing the forces imposed on the user to safe levels. In addition, tension is always kept on the lifeline, which helps reduce dragging, snagging, trips, and falls. Whether the application requires single or twin leg configurations, mounting to an overhead anchor, or for connection directly to harness, there are several models to choose from to suit a variety of applications.

Self-retracting lifelines (SRL's)

An SRL is an alternative to traditional shock absorbing lanyards and work a lot like a seat-beat - pull out slowly and extend the line; but don't you try to run with it.

These devices are specifically designed for professionals who work way up high - stopping falls within inches to allow great mobility.

Real quick - what's an SRL?
  • Retractable lifelines designed to stop a fall within inches.
  • Constantly under tension, but extends or retracts as the user moves up and down.
  • Offers greater protection then a shock absorbing lanyard.




PROTECTA SRL's utilize modern tech to maximize performance while minimizing cost. These devices are designed to stop a free-fall within inches, they are lightweight and built to last a long long time.

But what do they do?
  • They stack nicely when not in use - required very little storage space
  • Lightweight and portable
  • Easy to clean and inspect before use
  • Lifeline expands and contacts in reaction to the user
  • Steel components with corrosion resistant finish
  • Stops free-falls within inches

PROTECTA SRL's are low cost but highly effective in catching you should you fall.
