Description
Rectangular tube insert 50×80 mm, grey

The grey Rectangular tube insert 50×80 mm is a finishing component for closing the open ends of tubes and hollow profiles. It is made of polyethylene and sold individually, making it easy to select the exact number of inserts required for the job.
The internal section of the insert has ribs that adapt to the inside of the profile when pressed in, holding the insert in place. The flat rectangular flange with rounded corners covers the edge of the profile and gives the end a neat appearance.
Applications and selection
- protecting the ends of steel and aluminium profiles with a 50×80 mm rectangular cross-section
- finishing load-bearing structures, frames, balustrades and supports
- protecting the inside of the profile from dirt and debris
- versatile fit for profiles with different wall thicknesses thanks to the ribs
Polyethylene inserts are commonly used to protect profile ends because the material is lightweight and easy to work with during installation. When selecting an insert, check the nominal profile dimensions and wall thickness.

Installation
Press the insert into the open end of the profile until the flange rests against its edge. The ribs deform during insertion, ensuring a secure fit in profiles with a wall thickness within the specified range.
