SPRINGFIELD ARMORY Locking Seat Post — 2-3/8" Diameter x 12" Length, Anodized Marine Trac‑Lock Compatible

SPRINGFIELD ARMORY's 12" Locking Seat Post is a corrosion-resistant, anodized marine seat post with a secure latch designed to lock into Trac‑Lock swivel systems for reliable seating on boats.

Designed for anglers and boat owners who need a sturdy, weatherproof seating solution, this plug‑in seat post measures 12 inches from top to bottom and fits a 2‑3/8" diameter plug‑in base (bases sold separately). The anodized finish helps resist saltwater corrosion while the integrated latch locks the post into compatible Trac‑Lock swivels, keeping the seat stable in choppy conditions or when getting in and out of the boat.

How does this seat post keep a boat seat secure?

The seat post uses a spring‑loaded latch that engages the Trac‑Lock locking swivel or compatible 2‑3/8" plug‑in base. Once inserted and latched, the post resists vertical and rotational movement, delivering a dependable connection between seat and base.
