Attwood Marine Swivl-Eze 238 Series Seat Mount without Slider, For 2-3/8 in D Post

Overview

The Attwood Marine 238 Series is a group of boat seat mounts without slider adjustment for 2-3/8 inch D-post pedestal systems. These mounts are used between the seat and pedestal post, giving the seat a secure mounting point while keeping the hardware simple for helm, cockpit, casting deck, or passenger seating layouts.

The range covers stainless steel and plated steel versions, with 0° or 3° tilt depending on the configuration. Handle placement also varies, so the seat release can be matched to the way the seat is accessed on board. The 238 Series layout is a practical fit for replacement work or new seating installations where the boat already uses a compatible 2-3/8 inch pedestal post.

Key features

• Seat mount without slider for a cleaner, lower-complexity pedestal setup.
• Fits 2-3/8 inch D-post pedestal systems in the Attwood Swivl-Eze 238 Series.
• Available with 0° or 3° tilt, depending on the selected configuration.
• Handle orientations include left, right, and forward placements to suit different seat positions and cockpit layouts.
• Stainless steel and plated steel configurations are available for different installation needs and budget points.
• Handle shape is made for easy reach during seat adjustment or removal.

Variants

This 238 Series seat mount range varies by material, tilt angle, and handle position. Stainless steel versions are offered with 3° tilt and left or right handle placement, while plated steel versions cover 0° and 3° tilt options with left, right, or forward handle placement.

The main fit point across the range is the 2-3/8 inch D-post pedestal interface. For a clean installation, match the material, tilt, and handle orientation to the existing seat location, nearby side panels, console clearance, and the direction the user will naturally reach from while on board.

Compatibility and fit

This mount is meant for use with compatible 2-3/8 inch D-post pedestal components. It is not a universal replacement for every pedestal system, so the post diameter and series style should be checked before installation. Mixing seat mount hardware from different pedestal systems can lead to poor fit, unwanted movement, or a release handle that does not engage as expected.

Installation and use on board

Because this version does not include a slider, it works well where the seat position is already fixed by the pedestal location. That makes it useful for fishing seats, helm seats, cockpit seating, and replacement jobs where fore-aft travel is not needed.

Before mounting the seat, confirm that the handle has enough clearance to move freely and that the selected handle orientation is reachable from the normal seated or standing position. On boats used in saltwater or frequent washdown environments, routine rinsing and periodic inspection of the seat hardware help keep movement smooth and reduce buildup around the handle and post interface.
