>  Self Retracting Lifelines  >  Overview

​​

Backed by decades of proven field service for absolute confidence!

3M is the industry leader in multiple categories of fall safety equipment, including the development of reliable and versatile self-retracting lifelines (SRLs).

We developed the world's first self retractable lifeline over 60 years ago and have continued with innovative advances on lifeline systems that have been widely adopted across the industry—such as sealed designs, RSQ dual-mode functions, 3-way retrieval models and the impact indicator.

Our self retracting lifeline system's are recognized as the best, most durable and reliable of lifeline products available anywhere. Our SRL systems are backed by decades of proven field service in some of the most abusive environments known to man for absolute confidence and trust.

These self retracting lifelines (SRL's) are anchored overhead and extend and retract automatically, letting you comfortably move about at your normal speed within a recommended working area. Tension is always kept on the lifeline, which reduces dragging, snapping and trip falls.  Should a fall occur, a speed-sensing brake activates, stopping the fall and reducing the forces imposed on the user to safe levels.​

Various styles, configurations and lengths from 6 ft. (1.8 m) to 175 ft. (53.5 m) are available to suit almost any need.
