Koós Ball Bearing Swivel with Coastlock Snap Our products, marked with the Koós name, are characterized by quality and reliability. The durable steel swivel clips are extra strong and withstand the long-lasting load that often occurs when fishing for catfish. The defect of most average large swivels is that their material weakens prematurely, and it bends, or simply breaks, causing the loss of the fish. On the other hand, Koós swivels, are famous for their extra load-bearing capacity! The Ball Bearing Swivel, complete with a Coastlock Snap, is designed to provide quick attachment and quick replacement of rigs and wobblers. They are made of a durable material, so we can be sure of the load-bearing capacity of our equipment even when playing the largest fish.
