3-Way 90° Elbow Joint – Stainless Steel Tube Connector for Ø22 mm Rails

This three-way stainless steel elbow joint is a key component for building custom structures on your boat. Whether you are constructing guardrails, a bimini top frame, a canvas support arch, or other frameworks, this fitting provides a dependable connection for three tubes at a common point. The 90° angle and triple sockets allow you to create a solid rectangular joint – for example, connecting a horizontal rail to a vertical stanchion and a crosspiece. This makes the joint extremely versatile: you can form rigid corners in frames or create T-shaped branches in railing systems.

Made of solid AISI 316 stainless steel, the connector is built to withstand the harsh conditions of the marine environment. You won’t have to worry about corrosion, even with constant exposure to saltwater and humidity. The surface is polished to a mirror shine, giving your boat’s hardware a professional finish that matches elegantly with other chrome/stainless fittings. The socket inner diameter is tailored for standard Ø22 mm tubing – a size commonly used in boat railings and structures. Thanks to precise manufacturing tolerances, tubes slide in snugly with no play.

Installation & Use: The fitting features pre-drilled holes for set screws or pins, which allow you to lock the tubes firmly in the desired position. Before final tightening, it’s recommended to apply a dab of anti-seize or marine grease on the stainless screw threads to ease future disassembly and prevent galling. This elbow joint is suitable for:

• Building Railings & Lifelines: Connecting vertical stanchions to top rails and additional braces, providing 90° corner stability for guardrails around the deck.
• Bimini Tops & Canopies: Constructing a rigid frame for a sunshade – joins side bows and front bows with cross-bars to form a rectangular structure. This joint keeps the frame sturdy even under wind pressure on the canvas.
• Other On-Deck Projects: Fabricating frames for folding tables, equipment holders (e.g., rod holders rack), or support structures for solar panels above the cabin. The triple-elbow design offers creative freedom for any project requiring a strong 90° union.

In operation, the connector requires minimal maintenance – simply rinse it with fresh water along with the rest of your deck hardware to wash off salt and preserve its shine. If you need to reconfigure or take apart your structure, the set screws can be loosened and the joint reused multiple times without wear. This makes it a cost-effective, long-term solution for your boat’s needs.
