Double Bitt Bollard is one of the oldest bollards used in jetty, quay and wharfs. Because of its double horn shape, it is often called a twin horn bollard. It is designed with a narrow base to accommodate the limited dock space in the work area.

Double Bitt Bollard is a direct improvement of Single Bitt Bollard, which can accept multiple mooring ropes without affecting the mooring lines of adjacent ships. And concrete is optional to enhance the stability of the wharf. It is made of ductile cast iron or cast steel. These materials are strong and corrosion-resistant, allowing bollards to enjoy a long and trouble-free service life. Its mooring line capacity can reach more than 200ton, which can withstand use in harsh environments.

It is suitable for a lower angle, horizontal ±180°vertical +60°/-15. Besides, the horns on the double bitt bollard prevent ropes or wires from “climbing up” on the bollard during towing, and allow for easy and controlled checking.

The double bitt bollard provided by Boomarine has a good quality guarantee and a working life of up to 20 years. At the same time, we can also provide customized designs upon request. In addition, we also supply other types of mooring bollards. If you have any needs, please feel free to contact us.
