Description
Square tube insert 80×80 mm, black, wall thickness 5.0–8.0 mm

The black Square tube insert 80×80 mm is a finishing component that closes the open end of a hollow section. It is designed for tubes with a wall thickness of 5.0–8.0 mm, making it suitable for different tube variants with the same nominal dimensions.
The insert is made of polyethylene. The flange covers the edge of the tube, while the internal section with fins is pressed into the tube and holds the insert in place. Push-in inserts of this type are installed without additional fasteners by pressing them into the tube opening.
Applications and selection
- Closing the ends of square tubes in structures, frames and supports
- Finishing open tube ends in fencing and support structures
- The black colour complements dark tubes and structures in similar tones
- Sold individually, allowing you to order the exact number of inserts needed for the tube ends
When selecting an insert, measure the nominal external dimensions of the tube and its wall thickness. Push-in inserts fit correctly when the tube wall thickness falls within the range specified for the model.

Installation and use
Press the insert into the end of the tube until the flange rests against its edge. The fins inside the tube hold the insert in the opening, while the flange conceals the cut end of the tube. The polyethylene insert provides a durable finish for metal structures.
