Springfield’s Plug-In Fixed Post is a locking 2-3/8-inch seat post designed for use with a Trac-Lock Locking Swivel and any 2-3/8-inch Plug-In base, both sold separately.
High-strength aluminum construction with a powder coat finish stands up to regular helm or deck use without the corrosion a lower-grade material would eventually show.
At 15 inches from top to bottom, it’s a fixed-height option for a boat that doesn’t need an adjustable post, keeping the setup simpler and more affordable. Explore more seats, pedestals and slides.
