3/4″ Boat Seat Pin Post (6″ Height) — CLLOMAGY

The 3/4″ seat post pin post features a 6″ height and a 1.5″ exterior diameter, designed to fit most standard 7″ x 7″ pedestal mounts. The lock-in swivel design helps prevent accidental detachment from a boat seat pedestal, enabling reliable 360-degree rotation. Best for small to mid-sized boats where compact seating is preferred and quick-adjust seating is needed. Caution: shorter height may limit reach on taller seating bases or when additional clearance is required for deck hardware.
Attwood Lock’N-Pin 3/4″ Adjustable Pro-Post SP-2244-ADJ-T

This adjustable post extends from 25″ to 31″ and uses a 1.5″ diameter brushed aluminum extension with a threaded steel pin. It’s a strong option for adding seating to fishing, pontoon, or cruising boats, offering versatility for cockpit layouts. Best for buyers who need a taller seat height and a threaded locking mechanism for added security. Limitation: heavier and longer profiles may require more deck clearance and may not fit every compact cockpit.
Attwood Wedge 13-Inch Satin Anodized Post

With a fixed 13-inch height, this post is designed to integrate with the 2-inch Wedge system for secure locking and reduced seat detachment in choppy water. The satin-anodized aluminum construction resists corrosion in harsh marine environments. Best for boats where a consistent, elevated seating position is valued. Caution: fixed height means less adjustability for shorter or taller users.
Attwood Lock’N-Pin 3/4″ SP-2164 (Non-Threaded)

This 16″ tall, 1.5″ diameter post uses a non-threaded steel pin with the Lock’N-Pin system to prevent unintentional detachment. It offers strong value for those seeking a longer post without internal threading. Choose this if you need a taller, economical option with reliable locking. Limitation: non-threaded design may be less adaptable to some threaded bases or adapters.
CLLOMAGY 11″ Pin Post With Base Kit

A complete pedestal kit that includes an 11″ pin post (1.5″ diameter) plus a mounting 7″ x 7″ base plate and 3/4″ pin post. This kit is ideal for replacing older seats or adding a new seating area on bass, pontoon, or fishing boats. Best for boaters who want a solid, corrosion-resistant aluminum setup with reinforced ribs for higher load bearing. Caution: ensure your base plate mounting screws align with your deck structure.
Buying Guide: Key Considerations For Seat Post And Pedestal Selection
Choosing the right seat post or pedestal involves evaluating mounting compatibility, height needs, and locking reliability. Here are practical considerations to help you decide:
- Deck compatibility: Confirm your boat uses a standard 7″ x 7″ pedestal base and whether your base requires a threaded or non-threaded pin.
- Height needs: Consider how high you want your seated position from the deck and whether you’ll need adjustable heights or a fixed elevation.
- Locking system: Locking mechanisms (Lock’N-Pin vs wedge) affect security and detachment resistance in waves. Wedge systems are designed to minimize wobble; Lock’N-Pin focuses on detachability prevention.
- Material and finish: Aluminum and satin anodized finishes offer corrosion resistance in saltwater and freshwater environments; ensure the finish matches other fixtures on your boat.
- Weight and stiffness: Heavier posts can provide more stability but may require more deck clearance and mounting strength.
Frequently Asked Questions

Most commonly, a 7″ x 7″ pedestal base is used, which supports a range of 3/4″ to 1.5″ diameter posts. - Do I need a threaded or non-threaded pin?
Threaded pins offer more secure fastening in some applications, while non-threaded pins can be simpler to install and remove for temporary setups. - Is taller always better for seat posts?
Taller posts provide more legroom and visibility but require more deck clearance and sturdy mounting to prevent wobble. - Should I choose fixed height or adjustable height?
Choose adjustable height if you have multiple users or want to tailor seating height for different tasks or outfits of seats on your boat. - What maintenance is required for aluminum marine posts?
Rinse with fresh water after exposure to salt, dry fully, and inspect locking mechanisms for debris or corrosion, especially in harsh marine environments. - Can I mix posts from different brands?
