Boat Seat Swivel Mounting Base Recessed Center Swivel Seat Base Compact Size Rotating Mounting Post

This boat seat swivel mounting base is made of metal for a solid, dependable feel in marine seating applications. As boat hardware, it is built around a square top plate with rounded corners and a recessed circular center, giving the unit a clean, functional look while keeping the structure compact. The boat seat swivel mounting base serves as a rotating seat connection that lets the seat turn from side to side with the central rotating mounting post. That movement is useful when adjusting your position on the boat, facing different directions, or creating a more convenient seating arrangement during everyday use. Its swivel mounting plate includes slotted mounting holes near the perimeters, which helps with alignment during installation. The overall size measures 17.5 cm by 17.5 cm, with a 14.8 cm total height, while the post length is 12.5 cm and the post diameter is 1.9 cm. These dimensions provide a compact format that fits neatly into a boat seat setup without unnecessary bulk.
