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.



Nano-lok SRL

These little devices make a big difference when it comes to working at height.

The new Nano-lok SRL's are easy to install, smaller and even take more of a beating than the previous model could.

Next-gen Features
  • Installation is 60% quicker
  • Rubber cover lasts 4x longer than the previous model
  • 4ft. overhead fall clearance per OSHA 1910
  • ANSI Class A/B models limit falls within 24"
  • 6ft. fall clearance required on Class B SRL's
  • Knee-level of higher tie-off.

"Nano-lok SRL's are the lightest ANSI certified SRL that allows for knee level tie-off."
