Description
Square tube insert 20×20 mm, white

The white Square tube insert 20×20 mm is a finishing component for closing the open ends of hollow sections. Made of polyethylene, it creates a neat, flush finish when pushed into the tube.
The insert's shank has flexible ribs that adapt to the inside of the tube during installation and hold it in place, while the wide head covers the wall edge. The insert is designed for tubes with a wall thickness of 1.0–2.5 mm, so one size fits different tubes with a nominal dimension of 20×20 mm.
Applications
- Closing the ends of 20×20 mm square tubes
- Providing a neat finish to hollow sections after cutting
- Protecting the tube edge and interior from dirt
Push-in inserts of this type are used where a hollow section needs to be protected and neatly finished without additional fasteners. Polyethylene is a lightweight material commonly used for such products. The product is sold individually, allowing you to order the exact quantity required for the job.

Before ordering a larger quantity, check the actual wall thickness of the tube and compare it with the range given in the specification. A correctly sized insert enters the tube with noticeable resistance, and the head sits flush against its edge.
