Loose rails are a death trap. You’re hitting a swell, reach for the rail, and it wobbles like a drunk deckhand. Your safety line shouldn't be a suggestion. If your hardware is moving, you're already in the bilge. Fix it before you're swimming.

Cheap pot metal and plastic rubbish have no place on a seaworthy vessel. Use that nylon junk and the sun will bake it brittle in a season. One hard yank and it snaps. Then you’ve got rust bleeding down your gelcoat from low-grade 304 steel. It looks like a crime scene. Pitting eats the metal from the inside out. You can’t trust your life to hardware store scrap. Check the Marine Forecasts—the sea doesn't care about your budget.

Get the 316 Stainless Steel Boat Hand Rail Fitting - 45° Round Base (7/8"). This is the only way. It’s investment-cast 316 steel. Heavy. Solid. It won't bleed rust on your deck. This 45-degree angle is fixed for maximum structural rigidity. No moving parts to fail. It fits a standard 7/8 inch tube perfectly. Pair it with a Marine Offset Hinge - 316 Stainless Steel Heavy-Duty (85x40mm) or a 316 Stainless Steel Round Base 90° Boat Handrail Fitting (22mm/25mm) if you're running a different line. If you're securing a hatch nearby, don't forget a Marine Turning Lock - 316 Stainless Steel Flush Slam Latch (2"). Do it once. Do it right.

FAQ

Will this fitting rust in saltwater conditions?
No. Unlike 304 stainless, this fitting is constructed from high-purity 316 Stainless Steel, which contains molybdenum to specifically prevent pitting and crevice corrosion in high-salinity marine environments.
Is the 45-degree angle fixed or adjustable?
The angle is fixed at 45 degrees, precision-cast for structural stability. This ensures the handrail remains rigid and secure under the physical stresses of boat movement and passenger use.
What size screws should I use for the base installation?
The 66.7mm base features three countersunk mounting holes designed for #10 or M5 flat-head stainless steel wood screws or machine bolts, allowing for a perfectly flush installation that eliminates snagging hazards.
