Description
Square tube insert 120×120 mm, black

The black Square tube insert 120×120 mm is a practical finishing component for closing the open ends of hollow sections. It gives the structure a neat finish and helps prevent dirt from entering the tube.
The insert is made of polyethylene. The ribbed internal section slides into the tube and is held in place by a push fit, while the external flange rests against the end of the tube and covers the wall edge. This gives the tube end a neat appearance.
Application and selection
- Closing the ends of square tubes in load-bearing structures, supports and frames
- Finishing steel and aluminium tubes in black
- Installation without additional fasteners, by pushing the insert into the end of the tube
The tube's external dimensions and wall thickness determine the choice of insert, so it is advisable to compare them with the specification before ordering. The ribs compensate for minor dimensional differences inside the tube, while polyethylene is a lightweight material commonly used for this type of finishing component.

Construction
The insert consists of an external section that rests against the end of the tube and a ribbed internal section that slides inside it. The black surface complements dark steel and aluminium tubes.
