$35.34
$42.18
Springfield 3690001-SL Table Base
The Springfield 3690001-SL is a high-strength aluminum floor base built for the Thread-Lock 2-3/8" table post system. It's the foundation piece that mounts flush to your deck and accepts any compatible 2-3/8" Thread-Lock post, giving you a solid, rattle-free connection between your table and the floor.
The base measures 7" in diameter with a 5-3/4" bolt hole pattern, making it straightforward to template and drill. Total installed height is just 0.625", so it sits nearly flush with the deck surface. The satin finish on the aluminum gives it a clean, understated look that holds up well in a marine environment without standing out when the table post is removed.
This is the floor base only. The 2-3/8" Thread-Lock table post is sold separately, so make sure you have the post and table top to complete the setup.
Material: High-strength aluminum with satin finish
Base diameter: 7"
Bolt hole pattern: 5-3/4"

$106.00
$131.58
Springfield 3680013-CL Seat Base
The Springfield 3680013-CL is a 7" x 7" stainless steel locking seat base built for the Spring-Lock system. Full stainless steel construction means it handles the marine environment without complaint, whether it's sitting in a spray-soaked cockpit or a damp bilge area.
Installation requires a 4" hole in the deck for the below-deck portion of the base. Once mounted, it accepts any compatible locking Spring-Lock post, which is sold separately. The base includes a factory-installed rotational stop that limits seat rotation to comply with ABYC AD rating standards, so you're covered on the safety compliance side right out of the box.
The locking design keeps the seat post firmly in place at your chosen height, with no unwanted movement underway. This is the base only. A compatible locking Spring-Lock post is required and sold separately.

$55.40
$66.47
Springfield 3660017 Seat Base
The Springfield 3660017 is a 7" locking aluminum floor base built for stowable table post systems. When you want a table that can be set up and taken down quickly without leaving a post sticking up in the way, this is the base that makes it work. The locking mechanism holds the post firmly in place while the table is in use, and releases it cleanly when you're ready to pull the post and stow it.
The base is made from high-strength aluminum with an anodized finish, giving it solid corrosion resistance in a marine environment. It measures 7" in diameter with a 5-3/4" bolt hole mounting pattern. Installation requires a 3.5" hole in the deck for the below-deck portion of the base. Once installed, it sits flush and clean on the deck surface.
Compatible with any 2-3/8" stowable or tapered table post, which are sold separately. This is the floor base only.

Springfield King Pin Base 7" x 7" Tall SS Brass/Bushing #3630001-B
$74.64
$89.57
Springfield 3630001-B Seat Base
The Springfield 3630001-B is a 7" x 7" threaded stainless steel King Pin seat base with a brass bushing insert. The brass bushing is the detail that sets this base apart from a standard threaded base. It reduces wear on the post threads over time and makes for a smoother, more consistent thread engagement every time you install or remove the post.
The base has a satin finish and is built from square stainless steel, giving it a clean look and solid corrosion resistance for long-term use in a marine environment. Installation requires a 2-1/2" hole in the deck and 4" of clearance below deck for the base body. Once mounted, it accepts any threaded King Pin post, which is sold separately.
This is the base only. A compatible threaded King Pin post is required and sold separately.
Base footprint: 7" x 7"

$43.88
$52.65
Springfield 3620004 Seat Base
The Springfield 3620004 is a 6" x 8" rectangular stainless steel King Pin seat base with a nylon bushing insert. The rectangular footprint gives you a bit more flexibility when mounting in tighter or more oblong deck spaces where a square base might not fit as cleanly. The nylon bushing reduces friction and wear on the post threads, keeping the connection smooth over years of use.
The base has a satin finish and is built from standard stainless steel for solid corrosion resistance in a marine environment. Installation requires a 2-1/2" hole in the deck and 3" of clearance below deck for the base body. That 3" below-deck requirement is shallower than some other King Pin bases, which can be a deciding factor on boats with limited deck depth.
Compatible with any standard King Pin post, sold separately. This is the base only.
Base footprint: 6" x 8" rectangular
Material: Stainless steel with satin finish
Bushing: Nylon insert for smooth post engagement and reduced thread wear

$64.76
$77.71
Springfield 3300750-R1 Seat Base
The Springfield 3300750-R1 is a 9" D-shape Plug-In seat base made from high-strength aluminum with a satin finish. The D-shape design is purpose-built for mounting along a gunwale, console edge, or any location where a standard round base won't fit cleanly against a wall or rail. The flat side of the base sits flush against the obstruction, letting you position the seat closer to the edge than a round base would allow.
This is the R1 (right flat) version, meaning the flat side is on the opposite side of the notch. That orientation matters when you're planning your seat placement, so make sure the flat side lines up with the surface you're mounting against before ordering. The base measures 9" x 7" with an 8" bolt pattern.
Compatible with any 2-3/8" Plug-In post, sold separately. This is the base only.
Base size: 9" x 7" D-shape
Bolt pattern: 8"

Springfield 3300754-1 Seat Base
The Springfield 3300754-1 is a 7" x 7" stainless steel Plug-In seat base with a satin finish. It's built for the Plug-In post system and works equally well for above-carpet and under-carpet deck installations, so you're not locked into one mounting style depending on how your boat is finished.
The base has a 5-1/2" bolt pattern and requires a 3-3/4" hole in the deck for below-deck mounting. The stainless steel construction with satin finish handles the marine environment without issue, and the clean look works well whether the base is sitting on top of carpet or flush-mounted beneath it.
Compatible with any 2-3/8" Plug-In post, sold separately. This is the base only.
