90° Stainless Steel Rail Elbow Joint – AISI 316 (22 mm)

This 90° elbow joint is a crucial component for building or repairing sturdy railings on your boat. Crafted from marine-grade AISI 316 stainless steel, it offers exceptional durability and resistance to rust even in saltwater environments. It is designed to connect two 22 mm (7/8 inch) diameter tubes at a right angle, ensuring your railing structure remains strong and stable at the corners.

The interior of the elbow grips the tubing securely—usually via built-in set screws (Allen hex drive)—so once installed, the connection won’t slip or rotate under load. Its polished finish provides an attractive, professional look that matches other stainless steel hardware on your vessel.

Use Cases and Recommendations:

• Perfect for creating 90° corners in bow or stern railings, providing a rigid and safe perimeter on your boat.
• Commonly used in the frame of bimini tops, sprayhoods, or dodgers, connecting 22 mm support poles at right angles.
• Recommended for small to medium-sized boats (e.g., RIBs, runabouts, sailing yachts up to ~30 feet) that utilize 22 mm rail systems, to maintain structural integrity and longevity.
• When building a custom railing or replacing worn-out fittings, this elbow joint offers a reliable connection that will extend the life of your railing system.
• Installation is straightforward: slide the elbow onto the ends of the two tubes and tighten the integrated set screws with the appropriate hex key to lock it in place (for extra security in high-vibration areas, a drop of thread-locker can be applied to the screws).

By choosing a marine-grade AISI 316 fitting like this elbow joint, you invest in the durability of your boat’s railings. Your rails will withstand harsh marine conditions and retain their polished look, and your crew can move around the deck with confidence knowing the railing joints are solid and secure.
