DAWSON Self-Retracting Lifelines are designed using webbing, wire rope, or a cable that automatically retracts into a housing unit, never allowing for any slack in the line. Self-Retracting Lifelines are longer than lanyards and permit a larger working radius, even when using a fixed anchor point—which is typically overhead. A breaking mechanism inside the housing unit will arrest a worker’s fall, much like a car seatbelt. A self retractable lifeline is slightly heavier than a safety lanyard, and for those watching their bottom line, tends to be pricier. That said, they offer more mobility and fast-acting fall arrest capability.
