NRC&XRC Boat Hand Rail Fitting-60 Degree 1 Inch
Product overview: Precision cast 316 marine-grade stainless steel with a 60-degree base, designed for 1-inch tubing. Best for: adding angled hand rail transitions on aluminum towers or decks. Limitation: assumes standard 1-inch tube; verify fit with your exact rail diameter.
NRC&XRC Heavy Duty 316SS Hand Rail Fittings
Product overview: This heavy-duty 316 stainless steel hand rail fitting is specified for 7/8″ tubes with a 60-degree round base. Best for: upgrading smaller-diameter rails on aluminum boats that require robust support. Caution: ensure the 7/8″ tube specification matches your existing tubing for a tight fit.
Buying Guide
- Material matters: Stainless steel 316 is highly corrosion-resistant, ideal for saltwater use. For aluminum towers, confirm compatibility with aluminum tubing diameters and wall thickness.
- Tubing compatibility: Measure tubing diameter (commonly 7/8″ or 1″) and confirm the fittings’ bore size to avoid gaps or looseness.
- Connector type: Tees, jaw slides, deck hinges, and eye ends each serve different applications. Choose the type that matches your rail geometry and mounting surfaces.
- Finish and maintenance: Mirror-polished surfaces look clean but require regular care to prevent staining in harsh environments; brushed finishes may hide minor scuffs.
- Installation considerations: Some fittings are designed for easy detachment to reduce scratching during assembly. If frequent disassembly is expected, prioritize detachable designs.
FAQ
- What is the standard tubing size for boat rails?
Most fittings shown here fit 7/8″ or 1″ tubing; always verify your tube diameter before buying. - Are these fittings suitable for aluminum boats?
Yes, many are designed for aluminum and stainless steel frames, offering corrosion resistance and secure mounting. - Do I need stainless steel for saltwater use?
316 stainless steel provides superior corrosion resistance in saltwater, making it the preferred choice for harsh marine environments. - Should I choose a 90-degree or 60-degree fitting?
90-degree fittings are for right-angle connections; 60-degree fittings suit angled transitions. Select based on your rail layout. - Is a detachable tee beneficial?
Detachable tees reduce installation risk and minimize scratching during assembly, especially on larger projects.
