Sealed SRL's

Sealed-Blok SRL's are heavy-duty self retracting lifelines designed for use in the WORST conditions.

Specifically built to withstand saltwater or any other mucky moist location - they are completely sealed to prevent damage to internal components

  • Sealed Design - ensures efficient & safe operation under all working conditions.
  • Secondary Anchorage Point - Allows for second back up anchorage point.
  • Dual RSQ mode - Allows users to select between fall arrest and descent mode
  • Fast-line - Allows for quick lifeline replacement while out in the field

TD;LR - Sealed SRL's are ideal for use in harsh environments where moisture or tiny particulates can damage SRL's internal components.


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.
