Rebel™ self-retracting lifelines (SRL) with super-tough yet lightweight composite housings are built to last providing an economical fall protection solution without compromising performance or safety. These Rebel™ SRL's feature a 310 lb (141 kg) user capacity, and a robust design to ensure longevity. Rebel™ is designed with the worker in mind, featuring a stackable space-maximizing design, high-strength web lifeline and a built-in swiveling anchorage point. An SRL'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.
