Four Socket Cross - Square

Four Socket Cross: 4-Way Connector for Square Tubing Uprights

The Four Socket Cross is a high-strength square fitting designed to create a four-way connection centered around a vertical upright. With four sockets positioned at 90-degree angles, this fitting allows horizontal square tubes to intersect a vertical post in all directions, making it ideal for constructing multi-sided frames, support structures, shelving units, storage racks, and modular builds.

Crafted from galvanized cast iron, the Four Socket Cross offers long-lasting durability and corrosion resistance, suitable for both indoor and outdoor applications. Each socket includes a steel set screw to securely lock tubing in place, and installation is quick and easy with just a standard Allen wrench. No welding or specialized tools required. Designed specifically for 25 mm square tubing with a 2 mm wall thickness, this fitting brings stability, flexibility, and professional-grade performance to any square tubing project.

Key Features:

• Four-Way Connection: Connects four square tubes horizontally to a single upright, forming a cross-shaped joint.
• Ideal for Structural Frameworks: Perfect for racks, shelves, modular displays, and square tube-based construction.
• Tool-Free Installation: Assemble quickly with an Allen wrench. No welding or cutting needed.
• Heavy-Duty Build: Made from galvanized cast iron for maximum strength and corrosion resistance.
• Secure Fit: Includes steel set screws in each socket for a tight, reliable hold.
• Indoor & Outdoor Use: Built to withstand industrial, commercial, or exterior environments.
• Tube Compatibility: Designed for 25 mm galvanized steel square tubing with a 2 mm wall thickness.

The Four Socket Cross square fitting simplifies complex designs by enabling solid four-way connections. Helping you build smarter, stronger, and faster.
