3M Fall Protection has led the industry in the development of reliable and versatile self-retracting lifelines (SRLs). Once anchored, they extend and retract automatically, letting users move comfortably within an area while keeping lifeline tension. Should a fall occur, a speed-sensing brake activates, arresting the fall. Various styles, configurations and lengths are available to suit almost any need.
Our roots in self-retracting lifeline go back over 60 years and many now-common innovations have followed. Decades of field service have shown our self-retracting lifeline systems to be dependable and trustworthy.
