Loose rails are a death sentence. You’re in a heavy swell, grab the brightwork, and the fitting snaps. Now you’re overboard. Most boaters buy cheap, thin-walled scrap metal. It’s negligence. A weak rail isn't a handrail; it's a trap.

Generic fittings are bilge water. Chrome-plated zinc? Garbage. It pits in a week. Plastic? Don't make me laugh. Plastic is for milk jugs, not blue water. These cheap parts bleed rust streaks down your gelcoat and fail under load. If your hardware can't handle a deck-ape’s weight in a gale, get it off the boat. Check the BoatUS Foundation for safety standards before you kill someone.

Install the 90 Degree Marine Stanchion Elbow - 316 Stainless Steel (7/8", 1", 1-1/4"). This is engineered hardware. Cast AISI 316. It doesn’t just sit there; it survives. Whether you’re running a AirowMarine 316 Stainless Steel Plow Anchor - Mirror Polish (5kg-50kg) or just fixing a bow pulpit, your elbows must be solid.

FAQ

Will this elbow rust in saltwater environments?
No, this fitting is cast from premium AISI 316 Stainless Steel, which contains molybdenum to specifically resist pitting and crevice corrosion in high-salinity saltwater environments, outperforming standard 304 grades.
Does it require welding for a secure fit?
No welding is required. The design features integrated hex-head set screws that provide a high-torque mechanical grip on the tubing, allowing for a secure, permanent-feel installation with the flexibility of future adjustments.
How do I choose the right size for my boat rail?
Measure the Outer Diameter (OD) of your existing railing tube. We offer three precision sizes: 7/8" (22mm), 1" (25mm), and 1-1/4" (32mm) to ensure a seamless, slide-on fit with minimal clearance.
