3M PROTECTA Rebel self-retracting lifeline (SRL) line is built to last providing an economical fall protection solution without compromising performance or safety. Rebel SRLâ€-s feature a 420 pound (190 kg) user capacity, a robust design to ensure longevity and are available in lengths from 6 ft. (1.8m) to 100 ft. (30.5m). Available in either aluminum or composite housing models, these SRLâ€-s are also equipped with an ergonomic carrying handle that makes transportation to and from the job site easy. Rebel is designed with the worker in mind, featuring a stackable space-maximizing design and an impact indicator to provide easy verification of whether the equipment has been involved in a fall. An SRLâ€-s lifeline will extend as the user moves away, and retract automatically enabling the user to move about within a recommended working area at normal speeds. Should a fall occur, a speed sensing brake system will activate stopping the fall and reducing the forces imposed on the user to safe levels.
