The 2111-01-00 is an 11’ self retracting lifeline. The lifeline will automatically retract as the worker moves closer to the unit to keep fall distances to a minimum. The unit automatically locks when it senses a fall. It can be attached to a fall arrest d-ring on all OSHA compliant harnesses and anchor devices as a fall arrest device in a vertical or horizontal position and for leading edge work. Hardware for this model includes one standard double locking snap hook with a 3/4” gate opening and a double locking carabiner for attachment.
