Attwood Marine Pedestals - 238 Series
Attwood Marine Swivl-Eze 238 Series Pedestals: Engineered for the Water
When it comes to keeping boaters comfortable and secure on the water, few components matter more than a solid, reliable seat pedestal. Attwood Marine — a brand with over a century of marine engineering experience — has long set the standard for seating hardware, and their Pedestals - 238 Series lineup is one of the clearest expressions of that expertise. Built under the trusted Swivl-Eze name, these pedestals are designed specifically for boaters who demand stability, smooth operation, and long-term durability in demanding marine environments.
What Defines the 238 Series?
The "238" designation refers to the pedestal's signature 2-3/8-inch post diameter — a standard that has made this series widely compatible across a broad range of boat seat mounting hardware. But compatibility is only the starting point. Attwood engineers the 238 Series with a strength-style-corrosion-resistance philosophy that shows up in every component detail.
- Hard-Anodized Aluminum Tubes: The pedestal posts are constructed from super-hard anodized aluminum alloy, exceeding Type A driver-side requirements for lateral strength — meaning they hold up under real-world helm loads without bending or flexing.
- Bead-Blasted, Clear-Coated Bases: Socket bases are bead-blasted to close aluminum porosity, then clear-coated to resist scuffing and corrosion — an important detail for boats regularly exposed to saltwater spray and UV.
- Stainless Steel Springs: All internal springs are stainless steel, chosen specifically to resist the oxidation and pitting that would quickly degrade lesser hardware in a marine setting.
- Gear-Tooth Locking Slider: The adjustable models feature a gear-tooth lock mechanism that locks solidly into position yet disengages easily when height adjustment is needed — no wrestling with a wobbly seat mid-trip.
- Acetal Linear Bearings: The slider rides on low-friction acetal linear bearings, making height adjustments smooth and wobble-free even after years of use.
- Ergonomic Handles: Release handles are thoughtfully designed to be easy on the hands and positioned for effortless reach — a practical detail that matters after a long day on the water.
Fixed Height & Adjustable Options
The 238 Series covers a range of use cases. Fixed-height bell pedestals are available in multiple heights, offering a clean and stable solution for boaters who don't need on-the-fly adjustment. Adjustable models — including both manual and power pedestal configurations — let captains dial in their seat height with minimal effort. The power pedestal models feature a cable-actuated height mechanism and a clear-coat aluminum finish that coordinates visually with other 238 Series accessories.
ABYC Compliance and Safety Standards
Attwood's 238 Series pedestals are ABYC Code A0 compliant — the certified safety standard for open-water seating hardware — and are rated for safe use at the helm or driver position. This isn't just a checkbox; it reflects Attwood's broader commitment to designing products that meet or exceed the industry's highest regulatory standards, including USCG and CE requirements across their full catalog.
A System Designed to Work Together
One of the practical advantages of choosing the 238 Series is that it functions as a coordinated system. Bases, posts, seat mounts, and extension posts are all engineered to match, so boaters can mix and match components — or replace individual parts — without sacrificing fit or function. Whether you're doing a full seating upgrade or replacing a worn post, the 238 Series ecosystem makes the process straightforward.
