Description
Rectangular tube insert 50×80 mm, anthracite

The Rectangular tube insert 50×80 mm in anthracite (RAL 7016) closes the end of a hollow section and gives it a neat, uniform finish. It is made of polyethylene, a material commonly used for products pressed into tube openings.
The internal section of the insert has ribs and a core that fit inside the tube, while the external flange covers the tube edge and conceals its cross-section. Inserts of this type protect tube ends from dirt and prevent accidental contact with sharp cut edges. The insert is designed for tubes with a wall thickness within the range stated in the specification.
Applications
- closing the ends of rectangular hollow sections measuring 50×80 mm
- finishing structures and frames where tube ends need a neat appearance
- matching the anthracite RAL 7016 colour to dark structural components
Before ordering, check the nominal tube size and wall thickness, as these determine whether the insert fits correctly. Inserts are sold individually, allowing you to order exactly the quantity required for your project.
