Description
Square tube insert 40×40 mm, grey

The grey Square tube insert 40×40 mm is a finishing component for closing the open ends of tubes. It is suitable for support structures and frames where an open tube end requires a neat finish.
The insert is made of polyethylene. The internal part has ribs in the form of fins, while the flat external flange covers the edge of the tube and gives the end a neat appearance. Inserts of this type are pressed into the open end of the tube, with the ribs holding the component in place.
The tube wall thickness range allows the same insert size to be used with 40×40 mm tubes of different wall thicknesses. When selecting a Square tube insert, the nominal tube dimensions and wall thickness are essential, so these should be checked before ordering. The product is sold individually, making it easy to choose the quantity needed for a particular project.
- Closes the ends of 40×40 mm square tubes in structures and frames
- Provides a neat finish to the tube edge in a neutral grey colour
- Made of polyethylene, a material commonly used for covers and inserts

Inserts with a ribbed internal part are used to protect the open ends of hollow tubes against dirt entering and to give them a finished appearance. The grey colour complements neutral steel and aluminium structures.
