Description
Rectangular tube insert 80×140 mm, grey, wall thickness 5.0–7.0 mm

The grey Rectangular tube insert is a polyethylene finishing component that closes the open end of a hollow section. It is designed for sections with nominal dimensions of 80×140 mm and a wall thickness within the range specified.
The internal section of the insert has ribs that hold it in place when pressed into the tube. The wide external flange covers the tube edge and gives the end a neat, even appearance.
Application and selection
- Protecting the ends of rectangular tubes against dirt and preventing debris from entering
- Finishing steel structures, frames, support structures and equipment components made from hollow sections

When ordering for installation companies, it is essential to match the insert to the tube's external dimensions and wall thickness, as these determine how the ribs fit inside the tube. Inserts of this type are commonly used to provide a neat and durable closure for the ends of tubes and sections in load-bearing structures and equipment.
Polyethylene is widely used to manufacture tube inserts, and the grey colour complements typical steel structures. The insert is sold individually, allowing the exact number of end closures to be selected for the structure.
