3M Protecta Rebel personal self-retracting lifelines (SRL’s) represent a major improvement in economy line SRL’s. You can economically replace simple lanyards with the versatility and added safety of a 6' (1.8 m) SRL. Protecta personal SRL’s are ergonomically designed for ease of use and are ideal for direct connection to most harnesses. The compact and lightweight design is barely noticeable on your back and stays out of your way. In addition, tension is always kept on the lifeline, which reduces dragging, snagging and trip falls. This is a one leg ANSI Class B SRL.
