3-Way | Plastic T Joint Connector for Rectangular Tube & Wooden Batons | Various Sizes

This Strong Universal Plastic 3-Way T-Joint is the essential component for creating secure, perpendicular intersections in your rectangular hollow section (RHS) structures. Designed for both metal and wood, this T-shaped external fitting allows you to join a vertical or horizontal support to a continuous run, forming a clean 90-degree junction—perfect for adding internal shelving supports, bracing, or cross-members to your frames.

Snug fit: We automatically factor in a small tolerance, so please purchase the bracket/joint that exactly matches the outside dimensions of the tube you need this joint to fit. We will do the rest.

Engineered to fit popular metric and imperial rectangular sections, it is the heavy-duty, reliable connector you need for both professional workshops and demanding DIY frame building.

Structural Intersections for Rectangular Tube and Rectangular Box Section

This 3-way T-connector is a structural fitting designed specifically for creating 90-degree junctions for rectangular tubes. The T joint features a reinforced external gusset to ensure maximum structural integrity at the point of intersection. It is manufactured from high-grade Thermoplastic Polyester and significantly reinforced with glass fibre.

• Superior Junction Stability: Engineered to rigidly hold a straight 90-degree T-angle under load.

• Anti-Rotation Design: Specifically shaped for the rectangular profile to lock the tube in place, preventing rotational movement and wobble in the finished structure.

• High Environmental Resistance: Offers excellent resistance to chemicals and heat, ensuring durable performance in industrial workshops, commercial spaces, and outdoor applications.

The joint features an attractive, subtle frosted finish and provides a snug fitment, resulting in clean professional lines suitable for both functional structures and aesthetically visible retail displays.
