Springfield’s KingPin Base is built from stainless steel with a nylon bushing and a satin finish, giving a durable, corrosion-resistant foundation for a KingPin post.
It has a 3″ cup depth for a below-the-deck mount, requiring a 2-1/2″ hole in the deck for installation.
At 4×8, it’s built to pair with any standard KingPin post, sold separately, giving a complete seat mounting foundation when combined with the right post. Shop more seats, pedestals and slides.
