Description
Rectangular tube insert 10×20 mm, black, wall thickness 1.0–1.5 mm

The black Rectangular tube insert is a finishing component for closing the open ends of hollow sections. It covers cut edges and gives the structure a neat, even finish.
The internal section of the insert has ribs, while the external section forms a flat flange that rests against the edge of the tube once pressed in. Push-fit inserts of this type can be installed without specialist tools, making them suitable for finishing structures in batches.
Applications
- Closing the ends of rectangular hollow sections
- Finishing frames, frameworks and support structures
- Protecting open tube ends from dirt
- Providing a neat finish to visible tube ends

Selection and installation
Before ordering, check the nominal tube size and wall thickness and compare them with the dimensions table below. Selecting the correct insert size helps ensure a secure fit in the tube.
Press the insert into the open end of the tube until the flange rests against its edge. Polyethylene is commonly used for components of this kind: it is lightweight and resistant to moisture.
