The HWPS12 is designed to be a low maintenance device with a steel rope lifeline, terminated with an aluminum double action hook. The attachment anchorage point on the fall arrest block is a cast aluminum swivel eye ø16mm, suitable for connection via a standard karabiner connector, or a standard karabiner type connector with an anchorage sling.

The steel rope lifeline has been tested in a simulated fall over an edge and passed the German draft amendment EN360.
