Sea-Dog 316 Stainless Strap Hinge 4-1/8 in | 205390-1
Sea-Dog 316 Stainless Strap Hinge 4-1/8 in | 205390-1 — Product description
Sea-Dog's 316 stainless strap hinge is the bolt-it-on-and-forget-it kind of hardware. Four-plus inches of surface-mount hinge in true marine-grade stainless, sized for hatches, seat lids, and deck boxes where salt spray chews up cheaper hardware.
Sea-Dog's strap hinge is the kind of small hardware that quietly earns its keep. It's cut from 316 stainless steel, measures 4-1/8 inches long by 1 inch wide, and mounts flat to the surface of whatever you're hanging. This listing is for a single hinge, so order the count your project calls for. Most lid jobs use two, but a long hatch might want three for even support.
Strap hinges get their name from the long, narrow leaves that spread the load along the length of the hinge instead of bunching it up at a compact knuckle. That's what you want on a lid or a lightweight door that swings often. Think seat-box lids, deck storage boxes, live-well covers, small lockers, cabin doors, and gate panels. Anywhere you need a clean pivot and a bit of reach across the seam.
The material is the part that matters most out here. 316 stainless is the marine grade, the one with the added molybdenum that helps it shrug off salt spray and standing water far better than the 304 stainless you'll find on cheaper hardware. On a boat that lives in or near saltwater, that difference shows up a couple of seasons down the road when the bargain hinge is weeping rust streaks and this one still looks new. A quick freshwater rinse now and then keeps it that way.
Install is straightforward surface mount. The hinge sits on top of the two panels you're joining and fastens down through the leaves. Fasteners aren't listed as included, so plan to supply your own stainless screws or bolts sized to your material. Match the fastener metal to the hinge, stainless with stainless, and you won't set up any galvanic headaches down the line. If you're not sure what length fastener you need for your panel thickness, give us a shout and we'll help you sort it.

Frequently asked questions
Is this 316 or 304 stainless?
It's 316 stainless, the higher marine grade. The added molybdenum gives it better corrosion resistance in salt air and saltwater than standard 304 hardware.
Does it come as a pair or a single hinge?
This is a single hinge. Most lids take two, so order the quantity your project needs.
What are the exact dimensions?
The hinge is 4-1/8 inches long by 1 inch wide. It's a surface-mount strap hinge.
What's it good for mounting?
Seat-box lids, deck storage boxes, live-well covers, small lockers, cabin doors, and gate panels. Anywhere you need a clean pivot with a bit of reach across the seam.
Are fasteners included?
Fasteners aren't listed as included, so plan to supply your own. Use stainless screws or bolts to match the hinge and avoid galvanic corrosion.
Will it rust in saltwater?
316 stainless is built to resist salt corrosion, which is why it's the grade we like out here. Give it an occasional freshwater rinse and it'll keep looking new for years.
