Replace your worn out tire swing connector with the 3-1/2" Round Pipe Top Rail Tire Swivel. Coated in red enamel paint and complete with a rubber boot, the entire piece is designed to hold up to the outdoor elements. The rubber boot specifically protects the universal joint that allows for the 360 degree rotation. With four points of closure, the swivel will remain firmly clamped for years of use after initial installation.
For a smaller top rail, check out the 2-3/8" Round Pipe Top Rail Tire Swivel.
