Three Socket Tee - Square

Three Socket Tee Square Fitting: 90° Triple Connection for Square Tubing

The Three Socket Tee Square Fitting is engineered for complex builds that require strength, precision, and multi-directional connectivity. This heavy-duty fitting forms a rigid 90-degree connection between three square tubes, making it perfect for corner junctions, mid-span support, or multi-leg frames.

Designed with versatility in mind, the top socket allows a square tube to pass through entirely, ideal for continuous rail or beam applications, while the two side sockets feature independent set screws. This allows two different tubes to connect securely at a shared point, enabling mid-run connections without compromising structural integrity. Whether you’re building display structures, shelving units, or modular frameworks, this square fitting provides a rock-solid, corrosion-resistant solution.

Key Features:

• Three-Way Connection: Connects three square tubes at 90° angles, forming a T-junction with structural rigidity.
• Pass-Through Socket: The top opening allows a tube to slide completely through, offering adjustable or continuous runs.
• Dual Set Screws: Each of the two lower sockets includes its own set screw, allowing secure connection of separate tubes.
• Simple Installation: Installs quickly with a standard Allen wrench. No welding or special tools needed.
• Heavy-Duty Build: Manufactured from galvanized cast iron for exceptional strength and corrosion resistance.
• Indoor & Outdoor Use: Withstands both environmental and industrial wear and tear.
• Compatible Tubing: Designed for 25 mm or 40 mm square galvanized steel tubing with 2 mm wall thickness.

From industrial racks to architectural framing, the Three Socket Tee Square Fitting makes complex builds easier, stronger, and more adaptable.
