Wise - KingPin 7" x 7" Base Plate Only

The Wise KingPin 7" x 7" Base Plate Only is a replacement or standalone mounting foundation designed for boat seats and marine seating systems that utilize King Pin post installations. This base plate serves as the critical connection point between your seat pedestal and the boat deck, ensuring secure, stable seating in demanding marine environments. Whether you're upgrading an existing setup, replacing a worn component, or building a custom seating configuration, this base plate delivers the robust foundation marine applications require.

Manufactured by Wise Seats—a trusted name in marine seating solutions—this 7" x 7" base plate is engineered to work seamlessly with standard King Pin post systems, the industry-standard mounting mechanism for swivel and rotating boat seats. The square footprint provides broad weight distribution across the deck, reducing stress concentration and enhancing long-term durability in saltwater and freshwater environments. At 2.5 lbs, the base plate is lightweight yet structurally sound, constructed to withstand the rigors of constant use, vibration, and exposure to moisture and UV radiation typical in boating applications.

This base plate is ideal for boat owners, marine maintenance professionals, and custom seat installers who need a reliable deck-mounting solution compatible with King Pin pedestal systems. Installation involves fastening the plate to your boat deck using appropriately sized fasteners (not included), then mounting your King Pin post assembly directly onto the plate's center opening. Verify that your existing or planned seat pedestal uses a standard King Pin connection before purchasing to ensure compatibility with your marine seating configuration.
