The ball bearing swivels resemble their cousins - the barrel swivels in terms of design. However, unlike the less enduring barrel swivels, the ball bearing swivels are hugely effective due to the fact that ball bearings are used at the core of their design.As a result of the ball bearings, the ball bearing swivels can turn and twist in all directions freely without any friction, thus reducing the friction and pressure on the swivels and the line immensely even in the toughest fishing conditions.Breaking Strain 300lb
