CLGR® Steel Bobbin for Trawling Fishing, also known as Trawler Bobbin, Bobbins in steel.
These bobbins allow the net to glide easily over rough seabeds. This effective rolling action significantly reduces bottom friction, prolonging the trawl net's working life.
The solid steel construction provides excellent weight and stability, keeping the footrope firmly on the ocean floor. This ensures the net maintains proper shape and contact with the seabed for a higher catch rate.
Our steel bobbins perform reliably on diverse seabeds, from soft mud to hard rock and coral. They are a trusted choice for both inshore and deep-sea bottom trawling operations.
To help crews quickly identify different specifications during operating, we offer both blue and red color options for various thicknesses. This minimizes the risk of using mismatched rollers for specific ground gear.
Manufactured from superior mild steel, all bobbins feature a durable anti-corrosion finish to withstand harsh marine conditions. We offer a comprehensive range of standard sizes and bore diameters to fit different ground gear setups.
