Provide a solid, marine-ready foundation for seating and accessories with the Springfield Marine KingPin Standard Square Steel Base. Designed for durability, strength, and long-lasting performance, this 7×7-inch mounting base is built from rugged steel with a satin electro-coated finish to resist corrosion in fresh and saltwater environments.
The square base design offers reliable support for KingPin pedestals and a variety of marine seating and table applications—making it a great choice for fishing boats, center consoles, cruisers, and pontoon seating systems. Easy to install with through-bolt mounting, the Springfield KingPin base delivers a secure platform you can count on for years of dependable service.
KingPin Standard Design: Compatible with all standard KingPin non-threaded pedestals and power-poles.
Satin E-Coat Finish: An electrically applied coating that provides superior protection against rust and wear, perfect for deck mounting.
Heavy-Duty Steel Construction: Built to withstand the torque and weight of occupied seats during rough water conditions.
Flush Mount Profile: Requires a 3-inch hole in the deck for the socket, ensuring the top plate sits nearly flush to the floor to prevent tripping.
Universal Bolt Pattern: Uses standard mounting holes that match most pre-drilled boat floors.

Support: Ensure your deck has a sturdy backing plate or sufficient wood/fiberglass thickness to support the load of a seated passenger.
Sealing: Use a high-quality marine sealant (like 3M 4200) around the mounting screws and the underside of the plate to prevent water from leaking into your boat's sub-floor.
Fasteners: This base typically requires 1/4" countersunk bolts or screws (not included). Stainless steel hardware is highly recommended to prevent "bleeding" or rust stains on your carpet or vinyl.
