Offset Y hang belay point with 2 stainless steel fixing plates and equal length chains leading to the main ring to which a 12mm karabiner is attached and through which the belay rope then passes. This spreads the load to 2 fixings on different rows for uneven walls so the fixings are on the same plane. These should normally be installed with a 12mm resinned anchor into a suitable substrate (dependant on the quality of substrate).
