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 - whats 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.
TL;DR - Self-retracting lifelines connect a harness to an anchor and offers great fall protection than a simple lanyard.
Â
Work smarter, not harder.
Spending less time fixing lockups and simplifying inspections SIGNIFICANTLY increases productivity and morale.

Feature packed SRL
Ergonomic handle - Allow easy transport between job-sites and makes it easier to install overhead
Magnetic retraction control - Lifeline rewinds at a smooth pace, minimizing the chance of harm to people or equipment.
Dual label system - The extra label on the lifeline allows the user to access critical information without have to go all the way back to the housing to get it.
HI-VIS Shock Absorbers - Horizontal lifeline modals feature high visibility orange shock absorbers which makes it much easier to tell if workers are tied-off.
Fewer unintentional lock ups - After millions of tests 3M Fall Protection created a smart SRL with 29% FEWER lockups.
Swiveling Carabiner & Anchorage - Ensures that the user is not in any way limited in movement due to the SRL anchorage.
