Attwood Marine 238 Series Fixed Height Bell Seat Pedestal, 2-3/8 in Tube, Hard-Anodized Aluminum

Overview

The Attwood Marine 238 Series is a fixed-height 2-3/8 inch bell pedestal range for boat seating installations that need a solid deck-mounted base without an adjustable height mechanism. These pedestals use a hard-anodized aluminum tube on a 9 inch round aluminum base, with height options of 8 inches, 11 inches, and 12 inches in this listing. Each listed height is measured from the deck to the top of the seat mount.

This series is used for helm, cockpit, and fishing seating where a set seating position is preferred. The AO rating supports Type A/Operator use, so it can be used in helm or driver seating applications when installed with compatible 238 Series seating hardware and suitable deck reinforcement.

Key features

• Fixed-height 2-3/8 inch bell pedestal format for Attwood and Swivl-Eze 238 Series seating systems.
• 9 inch round aluminum base with a hard-anodized aluminum pedestal tube for wet cockpit and deck installations.
• ABYC AO classification for Type A/Operator seating, including helm or driver positions.
• Base surface is bead-blasted to close aluminum porosity, then clear coated to help resist scuffing and corrosion.
• Stainless steel spring components reduce corrosion risk inside the seating hardware.
• Height is measured from the deck to the top of the seat mount, which helps when matching an existing seating position.

Variants

This product is offered in multiple fixed-height configurations for different helm, cockpit, and fishing-seat layouts.

The variable attribute in this listing is pedestal height. The 2-3/8 inch 238 Series format, hard-anodized aluminum tube, 9 inch round base, and AO classification remain consistent across these three variants.

• 238908-1: Height 8 inches. This lower fixed pedestal keeps the seat closer to the deck, which can suit cockpit layouts where overhead clearance, console reach, or a lower seating position matters.
• 238911-1: Height 11 inches. This height gives a moderate seat rise for helm or fishing seating without adding an adjustable pedestal mechanism.
• 238912-1: Height 12 inches. This configuration adds one more inch over the 11 inch version for setups where sightline over the console or deck fit benefits from the extra height.

Compatibility and installation

The 238 Series is a matched seating hardware system, and these pedestals should be paired with compatible Attwood or Swivl-Eze 238 Series seat mounts and related components. Mixing with other manufacturers' pedestal parts is not recommended because fit, locking action, and seating rating depend on the matching post, mount, and base geometry.

Before drilling, confirm seat height at the helm or fishing position, check clearance for the seat shell and arm movement, and verify that the deck has enough backing structure for the loads created by passengers, turns, and rough water. Use fasteners and bedding materials appropriate for the deck material and exposure on the boat.

Materials and corrosion resistance

The pedestal tube is hard-anodized aluminum, and the base surface is bead-blasted and clear coated. That combination is useful in wet cockpit and fishing-boat areas where spray, sunscreen, fish residue, and regular cleaning can be tough on unfinished aluminum.

Use cases on board

This range is a practical match for anglers, center-console owners, and runabout owners replacing a fixed pedestal within the same 238 Series system. The shorter 8 inch version keeps seating low, while the 11 inch and 12 inch versions help raise the seating position for visibility at the console or comfort at a casting deck.
