Springfield Spring-Lock Fixed Pedestal Post 1640401
Springfield Spring-Lock Fixed Pedestal Post 1640401 — Product description
Springfield's Spring-Lock fixed-height post gives you a solid 13-1/2 inch seat mount that drops into a matching Spring-Lock base and locks in place. Satin stainless steel means it shrugs off salt spray season after season. It's the go-to swap when your old post is worn or you're rigging up a fresh helm or casting seat.
Springfield's Spring-Lock fixed-height pedestal post is the workhorse under a lot of helm seats and casting chairs. It stands 13-1/2 inches tall with a 1-3/4 inch post, the standard Spring-Lock diameter, so it drops straight into a matching Spring-Lock base and locks down. No wobble, no play. Just a solid mount for your seat.
The whole point of the Spring-Lock system is quick removal. When you want the deck clear for cleaning, fishing, or hauling gear, you release the post and lift the seat right out. Drop it back in and it locks again. You'll see this setup on center consoles, aluminum fishing boats, and pontoons alike. That's the convenience boaters have counted on Springfield for over the years.
This one's built from stainless steel with a satin finish, so it holds up to salt and spray without the pitting you'd get from a cheaper post. Fixed height means there's no telescoping mechanism to seize up or rattle loose. What you set is what you get, season after season.
It carries a 5 inch offset, which shifts the seat off-center from the base. That's handy when you need to nudge a seat toward the gunwale or clear a console without moving the whole base. And it's built to ABYC Code H-31 B, the standard that covers how pedestal seating handles load, so you're not guessing about whether it'll hold up under a full-grown adult in a chop.
One thing to know before you order: this is the post only. It seats into a Spring-Lock base, so you'll need a compatible base if you're starting from scratch. If you're replacing a worn post on an existing Spring-Lock setup, this is a straight swap, no drilling or new hardware needed. Not sure what you've got? Send us a photo of your base and we'll help you match it.

Frequently asked questions
Will this fit my existing Spring-Lock base?
If your base is a Springfield Spring-Lock with the standard 1-3/4 inch opening, yes, this post drops right in and locks. If you're not sure which base you have, send us a photo and we'll confirm before you order.
Is the base included?
No, this is the post only. It's designed to seat into a Spring-Lock base, sold separately. If you're replacing a worn post on an existing setup, you already have the base you need.
How tall is the post?
13-1/2 inches. It's a fixed height, so there's no adjustment, what you see is the seating height you get.
What does the 5 inch offset do?
It shifts the seat off-center from the base by 5 inches. That lets you position a seat toward the rail or away from a console without relocating the base itself.
Will stainless steel hold up in salt water?
Yes. The satin stainless build is made for salt-water use and resists the pitting and rust you'd see on a plated or cheaper post over time.
What is ABYC Code H-31?
It's the marine industry standard that covers how seats and pedestals are mounted and how much load they need to handle. This post is built to the H-31 B rating, so it's rated to hold up under normal seated use.
