Description
Rectangular tube insert 40×80 mm, black

The black rectangular tube insert for 40×80 mm profiles is a finishing component for closing the open ends of hollow profiles. It protects the inside of the profile from dirt and gives the end of the structure a neat appearance.
The internal section of the insert has ribs that enter the profile and press against its walls. This allows a single insert to fit profiles with different wall thicknesses within the range stated in the specifications. The external section covers the edge of the profile, and the insert is pressed into its opening.
The insert is made of polyethylene, a moisture-resistant material commonly used for finishing products. The black colour matches dark steel and aluminium profiles.
Applications
- Closing the ends of steel and aluminium profiles with a 40×80 mm rectangular cross-section
- Finishing frames, racks and support structures made from hollow profiles
- Protecting open profile ends after cutting on site or in the workshop

When selecting an insert, the profile's external dimensions and wall thickness are important. Ribbed inserts are selected so that the internal section enters the profile with noticeable resistance and the flange sits flush against its edge. For installation and manufacturing companies, this is a consistent solution for finishing rectangular profiles of this size.
