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

The green Rectangular tube insert 20×100 mm is a finishing component for closing the open ends of hollow sections. It is designed for tubes with a wall thickness of 1.5–3.0 mm, so one version fits several wall thicknesses.
Inserts of this type are fitted by pressing them into the tube opening. The ribbed internal section enters the tube and presses against its walls, while the external flange covers the tube edge, giving the end a neat, closed finish.
Applications
- Closing the ends of 20×100 mm rectangular tubes
- Finishing the ends of frames, racks and support structures made from hollow sections
- Protecting the open interior of the tube from dirt and debris
- The green colour allows the insert to be matched to structures where this colour is required
The insert is made from polyethylene, a plastic commonly used for products of this kind. It is sold individually, allowing you to order the exact quantity required – each open tube end requires one insert.

When selecting an insert, the important measurements are the nominal tube size, its wall thickness (R), the external flange height (C), the insertion depth of the internal section (H), and the core and rib dimensions. All these values are listed in the specification below to help you check compatibility with the tube before ordering.
