The HWB2 is designed to be a low maintenance device with a webbing 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 webbing lifeline has been tested in a simulated fall over an edge and passed the German draft amendment EN360.

The webbing lifeline is fitted a fall indicator to show use in fall situation.
