These versatile connectors are ideal for industrial, workshop, retail, and DIY structural projects.

Key Features & Benefits

Flat-Profile Design – Special 4-way flat shape that keeps connections compact and low-profile while joining square tubes securely at right angles.

Durable Clip-Together Construction – Two-piece plastic moulding that snaps together easily, simplifying assembly and reducing build time.

Optional Steel Core Reinforcement – Available with or without a steel core for extra strength and rigidity in heavier-duty applications.

Multiple Size Options – Compatible with common square tube sizes such as 20×20 mm, 25×25 mm, and 30×30 mm (with various wall thickness options), so you can match connectors to your specific tubing.

Tool-Free Assembly – Push-fit clip-together design means no welding or special tools required, saving time and cost on every build.

Versatile Use Cases – Perfect for shelving units, panels, frames, mobile displays, workshop structures, storage racks, exhibition stands, and custom project builds.
