Overview

The Attwood Marine 238352-1 is a 9 inch aluminum socket base with a cut-both-sides profile for the 2-3/8 inch 238 seating platform. It has an anodized finish and requires a 3 inch mounting hole, which makes it a direct fit choice for installations already built around matching 238 Series hardware.

This base is used within Attwood Swivl-Eze 238 Series seating systems and is interchangeable with LakeSport 238 Series socket base applications. The cut-both-sides shape changes the footprint compared with a full round base, which can be useful when the seat base location needs a little more clearance around the edge.

Key features

• 9 inch aluminum socket base with cut-both-sides footprint
• Anodized finish
• Requires a 3 inch mounting hole
• Fits Attwood Swivl-Eze 238 Series seating hardware
• Interchangeable with LakeSport 238 Series socket base applications
• Built as a matched-system component rather than a universal mixed-brand base

Compatibility and fit

This base belongs to the 238 Series family, so it makes the most sense when you are replacing an existing 238 base or building around matching Attwood Swivl-Eze 238 or LakeSport 238 posts, pedestals, and seat mounts. It is not intended as a universal base for unrelated pedestal systems.

Installation and setup

The base needs a 3 inch mounting hole, so it is worth checking the deck cutout and the clearance below the mounting surface before drilling or swapping hardware. On a refit, confirm the pedestal series first and match the base to the rest of the seating system instead of treating it as a generic replacement plate.

Use cases on board

This is a good match for helm, cockpit, or fishing-seat positions that already use the 238 platform and need a replacement socket base with the same system fit. The cut-both-sides profile also suits layouts where a full round 9 inch base takes up more deck space than you want.
