Provides high quality compliance. Offers complete freedom of movement while reducing trip fall hazards, dragging or snagging by expanding to 6 feet when taut and automatically contracting to 4 1/2 feet in reaction to the workers movements. The unique inner core begins to extend and absorb energy once subjected to a fall, and limits the fall arrest forces to safe levels. A built-in impact indicator provides easy visual evidence if the shock has been involved in a fall. Features high strength, durable and corrosion resistant materials to stand-up to demanding jobsites.
