T-Shaped Rail Connector Ø22 mm – Cast 316 Stainless T-Fitting for Boat Railings

The Ø22 mm T-shaped rail connector is an essential component for building and repairing boat guardrails and railings. Cast from high-quality 316 stainless steel, this fitting joins three tubes into a strong, rigid intersection that withstands both mechanical stresses (e.g., people leaning on the rail) and harsh weather conditions. Its polished finish not only looks good but also resists rust accumulation.

Construction & Installation: The connector has three cylindrical openings to accept Ø22 mm tubes – two opposite openings for the horizontal rails and one perpendicular for the vertical stanchion. Installation is straightforward: slide the fitting into position, align the tubes, and tighten the set screws. The body typically has threaded holes equipped with stainless grub screws that press against the tubing to hold it in place. For additional strength, one can drill through and insert cross-bolts or cotter pins as needed.

Applications: The 22 mm diameter is widely used on small and mid-sized boats – it’s a standard on many sailboats and motorboats for lifelines and bimini frames. T-fittings are needed wherever vertical rail posts meet the upper (and sometimes lower) horizontal rails. For example:

• At the bow pulpit of a yacht, connecting side rails to the upright posts, forming the forward safety rail.
• At the stern – for rails around the swim platform or transom.
• In bimini top and canopy structures – T-connectors join support struts and cross-bars at right angles, adding rigidity to the frame.
• Interior uses – occasionally utilized in modular interior constructions on yachts where stainless tubing connections are needed (due to their strength and aesthetics).

Advantages:

• Maximum Durability: The cast construction means the fitting is one solid piece with no welds – this eliminates weak points and gives it high structural integrity. It can take significant force or shock (e.g., from a heavy wave impact or accidentally hitting the rail with the anchor) without cracking.
• Long-Lasting Corrosion Resistance: AISI 316 is the top choice for marine environments – the connector will not rust even after years of exposure. This is critical for safety, as railings are a primary safety feature and must remain reliable.
• Aesthetic Appeal: The polished surface reflects the surroundings and seamlessly matches the yacht’s hardware. The fitting’s design is smooth and streamlined, which looks professional and doesn’t trap dirt or grime.
• Easy Maintenance & Adjustment: If the railing ever loosens or squeaks, simply re-tighten the screws. If you need to reconfigure the rail (for example, adding accessories or changing the layout) – the T-fitting can be loosened and repositioned without damaging the tubes.
• Security: A Ø22 mm stainless rail built with quality connectors provides crew and passengers with a sturdy handhold when moving around the deck. The T-joints ensure the railing structure behaves as a single unit – with no weak links that might bend or break under stress.
