Create strong 90° square tube connections with our Plastic Square 2-Way Corner Tube Connectors — engineered for quick installation and secure joins in structural frames, display systems, shelving, workshop fixtures, and more.

Product Highlights

Durable Two-Piece Clip-Together Design – Made from high-quality plastic for long-lasting performance, these connectors easily snap together to join two square tubes at a right angle.

Optional Steel Core Reinforcement – Choose versions with a steel core for extra strength where structural rigidity is critical, or lighter options without core for easier handling.

Perfect 90° Corner Joint – Ideal for joining two square tubes to form stable corner frames — a fundamental component in industrial racks, display structures, workstations, and DIY projects.

Wide Size Availability – Available in multiple popular tube sizes (such as 20×20 mm, 25×25 mm and 30×30 mm) — with many options in stock and others available to order.

Easy Assembly — No Welding Required – Connectors simply push together with tubing for a tool-free install that saves time and reduces labour.

Versatile Application – Great for DIY builders, fabricators, engineers and designers looking to construct reliable corner junctions in aluminium, steel, or box-section frames.

Why Choose These Connectors?

Our plastic 2-way corner tube connectors deliver consistent 90-degree alignment and strong joints without the need for complicated fabrication methods. Ready to use straight out of the box, they help streamline build processes and are suitable for a wide range of structural projects.
