Springfield KingPin™ 7" x 7" Offset - Stainless Steel - Square Base (Standard)

The Springfield KingPin™ 7" x 7" Offset - Stainless Steel - Square Base is a heavy-duty pedestal socket designed for marine applications where secure, corrosion-resistant mounting is non-negotiable. Built for boat seat pedestals, fishing chair bases, and other above-deck or below-deck installations, this offset socket handles the constant movement, vibration, and saltwater exposure that comes with years of serious time on the water. Whether you're upgrading a worn-out factory socket or retrofitting a custom build, this KingPin delivers the reliability that experienced anglers and boaters demand.

Constructed from solid stainless steel with a satin finish, the 7" x 7" base resists rust and salt spray far better than standard steel alternatives—critical when your rig spends months in saltwater or brackish environments. The offset bushing design accommodates non-centered pedestal posts, providing flexibility in seat positioning without requiring a perfectly aligned deck hole. A 3" cup depth securely captures and holds the pedestal post, while the nylon bushing reduces noise, vibration, and wear on both socket and post materials. The square base simplifies deck layout and drilling, and the below-the-deck mount option (requiring a 2½" hole) keeps fasteners hidden and clean.

This socket suits anglers upgrading aging chairs, tournament boaters needing redundant or repositioned seating, and restoration enthusiasts rebuilding classic fishing platforms. Installation is straightforward with basic fastening hardware; the stainless construction means no ongoing maintenance beyond occasional freshwater rinsing after saltwater trips. Weighing 2.45 lbs and measuring 9" x 3" x 9", it installs cleanly on deck or below without adding excessive topside clutter. For anyone serious about vessel longevity and seat stability, the Springfield KingPin™ offset socket is the professional-grade choice.
