Description
Square tube insert 30×30 mm, black

The black Square tube insert 30×30 mm is a finishing component for closing off the open ends of hollow tubes. For installation companies, it is a practical small component that gives structures a neat appearance and protects the inside of the tube from dirt.
The insert is made of polyethylene. The internal part with fins is pushed into the tube, while the flat external flange covers its edge and provides a neat finish. The product is designed for tubes with different wall thicknesses, making it suitable for several variants of 30×30 mm tube.
Applications
- Closing off the ends of square tubes in support structures and frames
- Finishing frames, support stands and equipment components made from square tubes
- Protecting open tube edges from dirt and damage
- Providing a neat, uniform black finish

Installation and selection
Inserts of this type are pushed into the open end of the tube until the flange rests against its edge. The fins on the internal part press against the tube walls and hold the insert in place. When selecting an insert, both the nominal tube size and wall thickness are important, so check these two parameters on the tube before ordering.
The insert is sold individually, making it easy to order the exact number required. The black polyethylene complements dark tubes and structures, while the smooth flange surface provides a neat finish to visible tube ends.
