Springfield Spring-Lock Locking Swivel Base | 1680203
Springfield Spring-Lock Locking Swivel Base | 1680203 — Product description
The Springfield Spring-Lock Locking Swivel Base is the deck-mounted swivel that your Spring-Lock pedestal post drops into. Black powder-coat, ABYC Class H-31 AD rated, with the standard 6-5/8 inch bolt pattern. It lets your seat turn and then lock in place, so you're not fighting a free-spinning chair every time the boat rolls.
The Springfield Spring-Lock Locking Swivel Base is the deck-mounted piece that ties your seat to your boat and lets it turn. If you're running the Springfield Spring-Lock pedestal system, this is the swivel that the post drops into. It bolts to the deck, accepts any locking Spring-Lock post, and lets the seat rotate and lock right where you want it.
Here's where it earns its keep. On a fishing boat you're constantly turning, to work a rod, reach the cooler, or keep an eye on the sonar. A swivel that spins freely all day gets old fast, especially in a chop. This one locks. Set the seat facing forward for the run out, unlock it and spin to fight a fish, then lock it again. That positive hold is the difference between a seat that fights you and one that stays put.
The base is finished in black powder-coat, so it takes the salt, sun, and spray that eat cheaper hardware. Springfield builds it to an ABYC Class H-31 AD rating, the standard that covers seats and mounting surfaces on boats. That rating matters when you've got real weight in the seat and the boat's pounding through waves.
The mounting footprint is 6-5/8 inches by 6-5/8 inches, the standard Springfield bolt pattern. If you're replacing an older Springfield swivel or building a new pedestal setup out of Spring-Lock parts, the holes line up. Four bolts through the deck and you're solid.
One thing to know before you order: this is the swivel base by itself. The seat and the Spring-Lock post are separate. That's the whole idea behind the Spring-Lock system. You pick the base, the post height you need, and the seat, and they all lock together. If you're not sure which post length fits your helm or casting deck, give us a call and we'll sort it out with you.
For anglers and cruisers alike, a locking swivel is one of those upgrades you don't think about until you've used one. Then you won't go back to a seat that spins on its own.

Frequently asked questions
Does this include a seat or pedestal post?
No. This is the locking swivel base by itself. In the Spring-Lock system the base, the post, and the seat are separate pieces you combine, so you pick the post height and seat that fit your boat.
What posts does it fit?
Any locking Spring-Lock post. That's the whole point of the Spring-Lock design, the post drops into this swivel and locks in place.
What's the mounting pattern?
The base footprint is 6-5/8 inches by 6-5/8 inches, the standard Springfield bolt pattern. If you're replacing an older Springfield swivel, the holes should line up.
Does the seat lock in position or spin freely?
It locks. You unlock it to swivel, then lock it again at the position you want. No free-spinning while you're underway.
What does ABYC Class H-31 AD mean?
ABYC H-31 is the marine standard that covers seats and mounting surfaces. Building to it means the base is rated to hold up under real seated weight and boat motion.
Will the black finish hold up to salt water?
The black powder-coat is made for exposed marine use. It resists the salt, sun, and spray that corrode uncoated hardware.
