Rectangular tube insert 20×100 mm, grey, wall thickness 1.5–3.0 mm

The grey Rectangular tube insert 20×100 mm is used to close the open ends of hollow sections. It protects the inside of the tube from dirt and debris and shields the tube edge from contact with its surroundings, giving the finished structure a neat appearance.

The internal section has ribs that slide into the tube and conform to its interior, while the flat external flange covers the tube edge. Inserts of this type are pressed into the open end of the tube without additional fasteners. They are made from polyethylene, a material commonly used for finishing components of this kind.

Applications

When selecting an insert, two factors matter: the nominal tube dimensions and the wall thickness, which determines how the ribs fit inside. A correctly selected insert sits securely in the tube, with its flange flush against the edge.

For installation companies and fabricators, the insert is a simple finishing component that gives tube ends a neat appearance and protects their interiors. Sold individually, it allows the required quantity to be selected for each job.
