Description
Rectangular tube insert 10×40 mm, grey

Grey 10×40 mm Rectangular tube insert is used to neatly close the open ends of rectangular tubes with nominal dimensions of 10×40 mm. It is made of polyethylene, and its smooth flange covers the edge of the tube, giving the structure a neat finish.
The insert's stem has transverse ribs that adapt to the inside of the tube when pushed in, holding the insert in place. The insert is designed for tubes with a specified wall thickness, so check the wall thickness of your tube before purchasing.
Practical applications
- protecting tube ends in support structures, frames and frameworks
- neatly finishing visible tube ends
- neutral grey colour, easy to match with light-coloured structures

Selection and installation
Inserts for hollow tubes are selected according to the tube's external dimensions and wall thickness, as these determine whether the insert fits correctly. To install, push the stem into the tube opening until the flange rests against its edge.
Polyethylene is a lightweight, moisture-resistant material commonly used to manufacture tube inserts and caps. The insert is available individually, allowing you to order exactly as many as needed to close the tube ends.
