Heavy Duty 4 inch casters with polyurethane wheels.
360 degree swivel and heavy duty wheels for long life.
2 7/8 x 1 3/4 inch mounting holes.
Note: these casters are not directly interchangeable with Showtime tables originally equipped with 2 inch casters, and due to the larger mounting plate, they will require some new holes drilled into the bottom of your table.
