Lock Your Seat Height — Stay Focused on the Water
The Springfield Plug-In 2-3/8" Fixed Height Locking Post is a replacement or upgrade post for the Plug-In pedestal system, built for boaters who want a set-it-and-forget-it seat height with the added security of a locking mechanism. Unlike a standard fixed post, this one locks in three distinct positions, so you can dial in your preferred height and know it won't shift underway.
Anodized aluminum construction means it handles saltwater, UV, and the general abuse of life on the water without corroding or fading. This is a post-only component — pair it with a compatible Plug-In base and a Trac-Lock swivel seat mount to complete your setup.
Key Features
- Fixed height post with locking in three positions for a secure, customizable fit
- 2-3/8" diameter — the standard Plug-In series size
- Anodized aluminum finish resists corrosion in saltwater and freshwater
- Compatible with any Plug-In™ base
- Designed for use with the Trac-Lock™ locking swivel seat mount
Best For
Boaters who want a fixed-height post with the peace of mind of a locking mechanism — ideal for helm stations and fishing seats where you don't want the post shifting position while underway. The three-position lock gives you flexibility during setup without sacrificing security once you're on the water.
Parts Desk Insights
This is the post only — you'll need a base and a seat mount to complete your pedestal setup. For a ready-to-go locking system, the Springfield Plug-In Locking 3-Piece Pedestal Set includes this post, a base, and a Trac-Lock swivel mount all in one package. If you need just the base, the Springfield Plug-In 9" Round Aluminum Base is the standard companion. For the swivel seat mount, the Springfield Trac-Lock Locking Swivel is the correct match for this post. If you prefer a non-locking swivel, the Springfield 2-3/8" Trac-Lock Non-Locking Seat Mount is also compatible.
