Protecta® 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 Protecta® SRL's feature a 310 pound (141 kg) user capacity, and a robust design to ensure longevity. Protecta® 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.
