Tractel - Blocfor® 50 ft. Leading Edge Self Retracting Lifeline -1/CS


The Blocfor® 50ft Leading Edge Self Retracting Lifeline provides freedom of movement to workers performing their job at various heights. The Leading Edge Self Retracting Lifeline  automatically takes up the slack in the wire rope, keeping it out of the way while minimizing the free fall distance, should a fall occur. In the event of a fall, the sudden jerk in the wire rope will activate the centrifugal locking mechanism, arresting the fall within 2 ft. (0.6 m).
