Sea-Dog 316 Stainless Steel Door Hinge, 3 x 1-1/2 In
Sea-Dog 316 Stainless Steel Door Hinge, 3 x 1-1/2 In — Product description
Sea-Dog's 316 stainless steel door hinge is built for the one job cheap hardware always fails at, staying rust-free in salt air. It measures 3 inches long by 1-1/2 inches wide and ships as a single hinge. Good for cabin doors, lockers, and cabinet fronts where you want hardware that still looks sharp after a few seasons.
Hinges are the hardware nobody thinks about until one seizes up or streaks rust down a nice teak door. Sea-Dog builds this one from 316 stainless steel, the grade you actually want near salt water. It measures 3 inches long by 1-1/2 inches wide and ships as a single hinge, so count your doors and order in pairs.
Why 316 matters out here: it's the marine-grade stainless, and it holds up to salt spray and damp bilge air far better than the cheaper hardware-store stuff. That means fewer rust streaks on your gelcoat and a hinge that still swings clean after a few seasons. We've seen plenty of boats where the door itself is fine but the hardware's a corroded mess. This is the part that fixes that.
Where does it go? Cabin and companionway doors, cabinet and locker fronts, hatch boards, head doors, anywhere below or above deck that opens and closes. The 3 by 1-1/2 inch footprint is a common butt-hinge size, so it's an easy swap for tired hardware or a clean choice on a new build or refit.
A couple of install notes from experience. Stainless is hard, so if you're driving new fasteners into hardwood, drill a proper pilot hole first and a little wax on the screw threads goes a long way. Use 316 stainless fasteners to match, because mixing metals near salt water is how you start a corrosion problem. And since this sells as a single, plan your order. Most doors want two hinges, and a heavy companionway door might want three. Space them evenly, dry-fit the door and check the swing before you drive every screw, and you'll end up with a door that opens smooth and closes flush every time.
It's not a heavy-duty gate hinge or a structural bracket. It's a clean, corrosion-resistant door hinge sized for the doors and lockers you live with every day on the water. Simple job, done right, in the one material that lasts.

Frequently asked questions
What grade of stainless is this hinge?
316 stainless steel, the marine grade. It stands up to salt spray and damp air far better than 304 or plain hardware-store stainless, which means fewer rust streaks near the water.
How big is it?
It measures 3 inches long by 1-1/2 inches wide, a common butt-hinge size.
Does it come as a pair?
No, it's sold as a single hinge. Most doors need two, and a heavy companionway door might want three, so count your doors before you order.
Where can I use it?
Cabin and companionway doors, cabinet and locker fronts, hatch boards, and head doors, above or below deck.
What fasteners should I use?
Fasteners aren't listed as included, so plan to supply your own 316 stainless steel screws. Match the metal to keep the whole assembly corrosion-resistant, since mixing metals near salt water invites problems.
Is it strong enough for a companionway door?
Yes for typical cabin and companionway doors. For a heavy door, add a third hinge to spread the load. It's a door hinge, though, not a structural gate or bracket.
