Attwood Lock'N-Pin Pedestals: A Secure 3/4 Inch Seating System
Attwood Marine has supplied boat hardware since 1893, and its Lock'N-Pin line shows how that experience translates into practical seating gear. The Lock'N-Pin system is a 3/4 inch pin-style pedestal design built around one core idea: keeping the seat mount, post and base firmly connected, even when a boat is running hard in chop. If you are browsing the full range of Pedestals - Lock'N Pin or exploring the wider Attwood Marine brand, this page focuses on where the two meet.
What Sets Lock'N-Pin Apart
The signature feature is the all-steel pin, which adds strength and durability to the pedestal connection. The design is also engineered to prevent unintentional detachment of seat mounts, posts and bases, which is a real safety consideration when a seat carries a passenger's full weight on a moving boat. Attwood states that Lock'N-Pin products exceed ABYC Standard H31.6.1, giving boaters and installers a recognized benchmark for seat pedestal performance.
The 3/4 inch system is positioned as an economical, proven option. It suits fishing boats, pontoon boats and cruisers, and it works equally well for adding seating to a bare deck or replacing worn components on an existing setup.
Posts, Mounts, Bases and Kits
Attwood approaches Lock'N-Pin as a modular system, so you can buy components individually or as a package. Options in the line include:
- Fixed-height posts in a range of lengths, with common sizes around 11 and 13 inches.
- Adjustable-height posts, including manually adjustable designs that let you tune seat height to the driver or the application.
- Pedestal kits that bundle a brushed aluminum post, a black e-coated seat mount with spring, and a base plate.
- Base plates in a common 7 x 7 inch footprint, offered in threaded and non-threaded versions, in aluminum or stainless steel.
- Finish options such as brushed aluminum, satin and camouflage, depending on the kit.
Many Lock'N-Pin components are made in the USA, and several are backed by a limited lifetime warranty, though warranty terms can vary by item, so check the specific product listing.
Shopping Considerations
Compatibility matters most with pedestal systems. Lock'N-Pin is a 3/4 inch pin design, and Attwood does not recommend interchanging its components with other manufacturers' products, so match posts, mounts and bases within the same system. Also confirm whether your deck requires a threaded or non-threaded base, the post height that gives comfortable seating relative to your helm or fishing deck, and whether a fixed or adjustable post suits your boat. Base plate material is another factor, since aluminum and stainless steel each offer corrosion resistance suited to marine use.
