Product details:

The Ultra-Lok self-retracting lifeline is a great addition to any fall arrest system, with 20 ft (6.1 m) of nylon webbing and self-adjusting disk brake to keep you locked onto your anchor. The gasket between the two halves of the thermoplastic housing prevents debris from getting into the device, while the all-steel components resist corrosion. The swiveling anchorage point prevents tangles, and the swiveling self-locking snap hook can be operated with gloves on.
