Whitecap 3443BP Nylon Rail Hinge, 7/8-Inch, Black
Whitecap 3443BP Nylon Rail Hinge, 7/8-Inch, Black — Product description
The Whitecap 3443BP is a black nylon rail hinge with a concave base sized for 7/8-inch round tube. It seats flush against the rail, resists salt and UV, and drills for 3/16-inch fasteners. Sold as a single hinge, it's a simple, corrosion-proof fitting for rails, frames, and canvas supports.
Whitecap's 3443BP is a black nylon rail hinge built for the round tubing you'll find on rails, frames, and canvas supports around the boat. The base is concave, so it sits flush against 7/8-inch tube instead of rocking on it. That's the detail that matters. A hinge that seats clean stays tight and doesn't chew at the rail.
Nylon's the right call here. It won't corrode in salt air, it won't weep rust onto your gelcoat, and it flexes without cracking when the boat pounds through chop. The black finish blends in with most hardware and hides the grime that shows up fast on white plastic.
It measures 2-3/8 inches long by 7/8 inch wide, and it's drilled for 3/16-inch fasteners. This listing is for a single hinge, so count your mounting points before you order. Simple part, but get the fit right and it'll outlast a lot of the metal around it.

Frequently asked questions
What size rail does this hinge fit?
The base is concave and sized for 7/8-inch round tube. That curve lets it seat flush against the rail instead of rocking on a flat spot, which keeps the fastener tension even.
Is this metal or plastic?
It's molded nylon. That's a deliberate choice for the water. Nylon won't corrode or weep rust onto your gelcoat the way some metal fittings do, and it flexes instead of cracking under load.
Does this listing include one hinge or a pair?
One. This part number is sold as a single hinge, so add up your mounting points and order the quantity you actually need.
What fasteners does it take?
It's drilled for 3/16-inch hardware. Stainless screws are the usual pick for anything mounted on a boat since they hold up in salt air.
