It's a Second Generation, ABYC H-31 AD design built to bolt down clean and spin free at the helm. Simple, code-compliant, and built to outlast a few seasons of salt.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Springfield Marine 1240629-L is a fixed-height boat seat pedestal built to do one job and do it for years. It's an 18-inch anodized aluminum post at 2-7\/8 inches in diameter, part of Springfield's Second Generation lineup, and it ships with a non-locking Trac-Lock swivel already on top. Bolt it down, drop your seat on, and you're rigged. Simple as that.\u003c\/p\u003e\n\u003cp\u003eWe like this one for center consoles, walkarounds, and any helm where you want a clean, solid seat mount without a lot of moving parts. The fixed 18-inch height is the sweet spot for a lot of boats. Tall enough to see over the console when you're standing off the seat, low enough to keep you out of the T-top when you sit down. If you've got a helm seat between 18 and 22 inches across, this post sits it right where you want it.\u003c\/p\u003e\n\u003cp\u003eThe post is high-strength anodized aluminum, and the base is a cast AC7A aluminum alloy with a matching anodized finish. That anodizing matters out here. It's the difference between a post that still looks right after a few seasons and one that chalks up early. We still tell folks to rinse the base and post with fresh water when they hose the boat down, especially if you run in saltwater. Salt loves to sit at the floor joint. A weekly rinse keeps it honest.\u003c\/p\u003e\n\u003cp\u003eThe base is a 9-inch round plate, which spreads the load nicely on a fiberglass floor. On a solid glass or cored deck with proper backing, four stainless bolts through the base is all it takes. On thinner floors or aluminum decks, we'd add a backing plate and large fender washers underneath. That's what keeps you inside the ABYC H-31 seating load spec and keeps the deck from flexing under you when you drop into the seat at speed. This pedestal is built to ABYC Code H-31 AD, so the design's there. You just have to back it up on your end.\u003c\/p\u003e\n\u003cp\u003eThe Trac-Lock swivel on this model is the non-locking version. That means the seat spins freely, a full 360 degrees, no detents and no lever to release. It's great for a fishing cockpit where you're turning to work a rod or reach the cooler behind you. If you run offshore and want the seat to hold a heading in a beam sea, know going in that this one rotates free. Some folks add a friction washer to add a little drag, and Springfield makes a locking Trac-Lock version if a fixed heading matters more to you than free spin.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward if you take your time. The post wants a clean 2-7\/8-inch hole for a flush floor mount, so use the right hole saw. An off-size hole is the number-one cause of a wobbly pedestal. Mark your base, drill your bolt holes, bed everything in a marine sealant, and torque it down evenly. Grease the swivel bearing once a season and it'll keep spinning smooth for years. Skip that and the bearing can get stiff over time.\u003c\/p\u003e\n\u003cp\u003eOne note on fit. This is a Second Generation post, and the 2-7\/8-inch diameter is Springfield's heavy-duty size, not the lighter 2-3\/8-inch pedestal. So make sure your base plate or floor cutout matches the bigger post. If you're replacing an older 2-3\/8 setup, you're changing the floor mount too. Measure twice before you cut.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anybody rerigging a helm or leaning-post seat who wants a proven, code-compliant fixed pedestal and doesn't need height adjustment. It's not the pick if you share the helm with folks of very different heights, or if you want to drop the seat down for towing under a low garage door. For that you'd want an adjustable post. But if 18 inches is your number, this is a clean, honest piece of gear that'll outlast a lot of the boat around it.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e18-inch fixed post height, the sweet spot for most center console and walkaround helm seats\u003c\/li\u003e\n  \u003cli\u003e2-7\/8-inch high-strength anodized aluminum post for heavy-duty seating loads\u003c\/li\u003e\n  \u003cli\u003e9-inch round cast AC7A aluminum alloy base spreads the load across the deck\u003c\/li\u003e\n  \u003cli\u003eNon-locking Trac-Lock swivel gives free 360-degree rotation for working a fishing cockpit\u003c\/li\u003e\n  \u003cli\u003eBuilt to ABYC Code H-31 AD, the marine standard for installed seating systems\u003c\/li\u003e\n  \u003cli\u003eAnodized finish on post and base resists saltwater corrosion and chalking\u003c\/li\u003e\n  \u003cli\u003eSecond Generation heavy-duty design, not the lighter 2-3\/8-inch pedestal\u003c\/li\u003e\n  \u003cli\u003eFixed-height simplicity means fewer moving parts and nothing to fail under you\u003c\/li\u003e\n  \u003cli\u003eShips with the swivel already fitted, so you bolt it down and drop your seat on\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Springfield Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat is the post height and diameter?\u003c\/summary\u003e\n    \u003cp\u003eThe post is a fixed 18 inches tall and 2-7\/8 inches in diameter.
