90° Round Rail Base – Stainless Steel (AISI 316)

This 90° round rail base is a robust mounting platform for boat railings or bimini support poles. Cast in marine-grade 316 stainless steel with a round flange, it’s ideal for attaching a vertical railing (stanchion) to a horizontal surface at a right angle. The base has a smooth mirror polish, enhancing your boat’s aesthetics while preventing corrosion. Designed to fit standard tube diameters (available in 22 mm and 25 mm versions), it features a deep socket that cradles the tubing securely. Three countersunk screw holes in the round flange ensure the load is distributed evenly and the base is firmly anchored to the deck.

Key Features:

• Solid Construction: One-piece stainless steel base with round flange (approx. 66–69 mm diameter) for maximum strength and stability.
• Angle & Size: Holds rail tubes at 90° (vertical). Compatible with Ø22 mm or Ø25 mm railing tubes – choose the size that matches your rail for a snug fit.
• Premium Material: AISI 316 stainless steel, polished to a high shine. Completely rust-resistant, even in coastal and offshore environments.
• Easy Installation: Three pre-drilled holes for mounting screws/bolts. The symmetric round shape allows easy alignment and is ideal for gunwales, bow/stern pulpits, or console railings.
• Secure Grip: The base’s tube socket is precision-made to match the tube diameter, providing a tight grip. A locking screw (grub screw) is typically included on the side to fix the rail in place (prevents rotation or pull-out).

This rail base is commonly used on sailboats and powerboats to install or replace stanchion bases for lifelines and handrails. It’s also perfect for bimini top support poles or other structures where a railing meets the deck at 90 degrees. The mirror-polished finish not only looks great but also means less maintenance – just rinse off salt and it will keep shining. When you need a reliable, long-lasting base to secure a railing post on your boat, this round 90° stainless steel base is a top choice among boaters and marine professionals in Bulgaria and beyond.
