LGRIG® Cast Iron Ball Footrope Gear, also known as Trawler Bobbin.
To keep fishing nets weighted on the seafloor during trawling, fishermen historically used heavy devices such as the trawler bobbin.
These Iron balls or rollers are attached to the ground gear of the net, allowing it to roll smoothly over the seabed, reduce snagging, and minimize direct contact with the bottom.
This Iron Ball is cast for durability and available with either a Black Painted or Self-colored (natural) finish. Both options provide a robust and long-lasting product.
How did fishermen keep their fishing nets on the sea bed as they trawled? They used huge weights like this trawler bobbin.
Trawl nets have bobbins or rollers on the ground gear to allow the net to move over the sea floor without snagging and to minimize bottom contact.
