Attwood Marine Lock'N-Pin Pro-Post Boat Seat Post, 25-31 in, 3/4 in Pin, 1.5 in Diameter, Brushed Aluminum, Steel Pin

Overview

The Attwood Marine Lock'N-Pin Pro-Post is a manual adjustable boat seat pedestal post for 3/4 in Lock'N-Pin seating systems. It adjusts from 25 in to 31 in in height and uses a 1.5 in diameter brushed aluminum post with a steel pin, giving boat owners a practical replacement or upgrade point for compatible fishing, pontoon, and cruising boat seating layouts.

This post is built for stand-up style seating positions where height adjustment matters, such as casting, watching lines, or moving between seated and elevated deck use. The Lock'N-Pin system locks the seat mount, post, and base together to help prevent unintentional separation during normal boat movement.

Key features

• Manual height adjustment from 25 in to 31 in for setting a comfortable stand-up seating position on deck.
• 3/4 in Lock'N-Pin connection works with compatible Attwood seat mounts and bases in the same system.
• 1.5 in diameter brushed aluminum post gives the pedestal a clean finish while keeping weight manageable.
• Steel pin construction supports the locking connection between the post and matching seat hardware.
• Lock'N-Pin design helps prevent accidental detachment between the seat mount, post, and base.
• Type B rated seating component for use in positions not used as a helm seat and at speeds not exceeding 5 mph.
• Available in threaded and non-threaded versions to match the base and seat hardware already installed on the boat.

Variants

This product is offered in two configurations that share the same Lock'N-Pin Pro-Post format, manual adjustment range, brushed aluminum post style, and 3/4 in pin system.

The difference between the variants is the threading style. Matching the threaded or non-threaded version to the existing seat mount and base is important for proper fit in an Attwood Lock'N-Pin seating setup.

• SP-2244-ADJ, Non-threaded threading. This version suits compatible Lock'N-Pin bases and mounts that use the non-threaded pin connection.
• SP-2244-ADJ-T, Threaded threading. This version suits compatible Lock'N-Pin bases and mounts that require the threaded pin connection.

Compatibility and fit

This pedestal post is intended for Attwood 3/4 in Lock'N-Pin seating systems. Before installation, compare the threading style, pin size, post height range, and base style with the hardware already on the boat. A matching seat mount and base are needed for the lock function to work as intended.

The 25 in to 31 in height range is commonly used for elevated deck seating rather than low cockpit seating. Because it is a Type B component, it should not be used as a helm seat or in applications where the boat is operated above the stated speed limit for that rating.

Installation and use

The post is made for drop-in use with compatible Lock'N-Pin components. Once the correct threaded or non-threaded version is matched to the base, the pin connection locks into place so the seat hardware stays joined during normal boarding, fishing, cruising, and dockside movement.

Height is adjusted manually, which keeps the setup simple and avoids wiring, switches, or powered lift parts. This makes it a good match for boats where a straightforward pedestal post is preferred for fishing seats, removable deck seats, or replacement seating hardware.

Maintenance and care

Rinse the post and pin area with fresh water after saltwater use, especially around the locking connection where sand and salt can collect. Check the pin, locking action, and mating base regularly so the seat stays secure and adjusts smoothly through the height range.
