Description
Rectangular tube insert 20×40 mm, anthracite

The Rectangular tube insert 20×40 mm in anthracite (RAL 7016) closes the open end of a hollow section and gives it a neat, finished appearance. For installation companies, it is a practical finishing component for support structures, frames and bases made from rectangular tubing.
The ribbed internal stem presses against the tube walls, holding the insert in place. The external flange covers the edge of the tube and conceals the cut surface. The design is suitable for tubes with a wall thickness of 1.0 to 3.0 mm.
Material and colour
The insert is made of polyethylene, a material commonly used for tube finishing components. The anthracite colour (RAL 7016) complements dark structures, frames and tubes powder-coated in grey.

Selection and application
- protecting the open ends of 20×40 mm rectangular tubes
- finishing frames, stands and bases made from rectangular tubing
- neatly closing the cut end of a tube
- preventing dirt from entering the tube
The insert is sold as a single piece, making it easy to order the exact quantity needed for a specific project. Before installation, check the nominal dimensions and wall thickness of the tube, as these determine whether the insert fits correctly.
