ISO13797 Cruciform Bollard is a type of ship mooring fittings installed on board, to belay the mooring and towing rope. It is based on ISO standards and is made of high-quality steel tubes and steel plates, suitable for steel wires and traditional ropes, and can be used on decks or docks.

The surface of ISO13797 Cruciform Bollard is treated with a primer, and it can also be galvanized and painted on request. Besides, the surface is coated with an anti-corrosion protective coating, which has a good anti-corrosion performance. Its nominal size ranges from 150mm to 400mm, and weight ranges from 37KG to 165KG. Cause its safe working load is small, ranging from 78kN to 736kN. So it is only used for small ships equipped with steel wire ropes, and is not suitable for large ocean-going sailboats.
