DBI-SALA kernmantle rope lifelines have a twisted 3-strand design to optimise strength, durability and flexibility for supporting a worker and sustaining the force of a fall. These lifelines feature a built-in self-locking snap hook, at one end, to ensure secure connections. They conform to OSHA 1910.66, OSHA 1926.502, Capital Safety Gen. Mfg. Req., ANSI A10.32, ANSI Z359.1 Standards and are available in lengths ranging from 30 to 100 ft. When the requirement is to secure workers on I-beams, the brand's horizontal lifeline systems are an ideal choice because of their additional stanchions, built-in winch and pre-tension & impact indicators.
