3-Way 90° Elbow Joint (Stainless Steel for Ø25 mm Tube)

This 3-way 90° elbow joint is a crucial component for building stable tubular structures on your boat. It allows you to easily connect three 25 mm (1 inch) tubes at a right angle, forming a strong corner joint without the need for welding. Made from AISI 316 stainless steel, the fitting is fully resistant to saltwater and will not corrode or weaken over time. Its polished finish gives a professional appearance and matches your boat’s other stainless/chrome hardware. Internally, each leg of the joint has a set screw that tightens against the tube, locking it in place. This enables easy assembly and adjustments if needed, as well as a smooth exterior with no visible fasteners.

• Perfect for biminis and canopies: This elbow is widely used in bimini top frames and sun canopies, where four such corner pieces form a rectangular frame. Thanks to its strength, it keeps the canvas taut and the frame steady even in strong winds or at high boat speeds.
• Applications in railings: It’s indispensable for constructing bow and stern railings and grab handles. The elbow provides a rigid 90° joint between horizontal and vertical rail sections, ensuring the railing won’t wobble or bend when leaned on.
• Handles loads with ease: Whether in choppy waters or when someone grabs the frame, the joint absorbs the stress without deforming. The AISI 316 steel is extremely robust and is used in professional marine structures – it withstands the vibrations and shocks associated with boating.
• Easy assembly & adjustment: Installation requires no special skills – simply insert the tubes into the joint and tighten the concealed screws. This means you can build an entire frame with basic tools and disassemble or tweak it if needed (for example, to re-tension fabric or replace a section).
• Industry standard: The 25 mm (1") diameter is a common standard for many boat frames and accessories. This joint is compatible with Osculati and other leading brands’ tubing systems, making it a universal part for repairs or new projects. Investing in stainless fittings like this ensures a long-lasting result with minimal maintenance down the line.
