Springfield KingPin™ 4" x 8" - Stainless Steel - Rectangular Base (Standard)

The Springfield KingPin™ 4" x 8" Stainless Steel Rectangular Base is a heavy-duty deck mount system engineered for boats requiring a below-deck fastening solution. This stainless steel base accepts standard KingPin™ posts (sold separately) and delivers the corrosion-resistant construction critical for saltwater and freshwater marine environments where exposure to moisture and spray can compromise inferior materials.

The 4" × 8" footprint provides a stable mounting surface with a 3" cup depth designed to seat mounting posts securely. Installation requires a 2½" hole in the deck, with the bushing-equipped base sitting below the surface to minimize obstruction. The satin finish on stainless steel resists fingerprints and maintains a clean appearance while reducing glare in bright conditions—important for anglers who spend extended time on the water. At 1.75 lbs, this base adds minimal weight while handling the mechanical stresses of rod holders, fighting chairs, or other deck-mounted equipment in both light tackle and heavy-duty offshore applications.

This rectangular base suits boaters and anglers who need permanent, below-deck mounting for fishing gear, fighting chairs, rod storage, or specialized deck hardware. Weekend fishermen and serious offshore operations both benefit from the corrosion resistance and load capacity Springfield Marine built into this system. The modular design means you select the KingPin™ post height that matches your specific deck layout and functional requirements, allowing flexibility across different boat configurations.

Springfield Marine's KingPin™ system is well-established in the boating market for below-deck fastening applications. This base pairs with standard KingPin™ posts to create a modular mounting platform, giving you the option to customize post height and configuration without replacing the deck mount itself. Verify compatibility with your specific KingPin™ post model before purchasing.
