Boat owners, this Springfield Kingpin Power-Rise post is exactly what you need for comfortable seating on the water! The threaded pin design makes installation secure and straightforward.

The 360-degree rotation means you can always position yourself perfectly for fishing, driving, or just relaxing. Made with the highest grade materials to withstand marine conditions - we're talking corrosion resistance and durability that lasts season after season. Works with threaded Kingpin bases and is built to handle the movement and vibrations of being on a boat. Whether you're installing it on a fishing boat, pontoon, or runabout, this post gives you that flexibility to sit or stand comfortably throughout your day on the water.
