Description
Square tube insert 150×150 mm, brown

The brown Square tube insert is a finishing component used to close the ends of hollow sections. Made from polyethylene, it is pressed into the tube opening to cover the exposed end.
The internal section of the insert has ribs that press against the tube walls when inserted. The wide external flange covers the tube edge and provides a neat finish.
Applications
- Closing the ends of square steel and aluminium tubes
- Finishing support structures, fences, shelters and frames
- Covering exposed tube ends after cutting, for example at the ends of beams and posts
- The brown colour helps maintain a consistent appearance with structures in similar tones
Polyethylene inserts are commonly used to protect open ends of hollow sections from dirt and to cover sharp edges left after cutting. Polyethylene is a lightweight, moisture-resistant material, making it well suited to outdoor structures.
The insert is sold individually, making it easy to order the exact quantity required for a project. When selecting an insert for a specific tube, consider the nominal tube size and wall thickness given in the specification below.

Square tube inserts are pressed into the tube end until the flange rests against its edge. The ribbed internal section holds the insert in the tube, while the smooth outer surface provides a neat finish to the structure.
