Description
Rectangular tube insert 40×70 mm, anthracite

The Rectangular tube insert 40×70 mm in anthracite (RAL 7016) is a finishing component for closing the open ends of hollow sections. It neatly conceals the tube opening and gives the structure a tidy appearance.
The insert consists of a flat flange that covers the edge of the tube and an internal section with ribs. The ribs press against the tube walls and hold the insert in place, while the flange provides a neat, even finish at the edge. Made of polyethylene, a material commonly used for push-in inserts, it allows the internal section to flex for a secure fit.
Applications and selection
- Closing the ends of rectangular tubes in frames, bases, supports and other structures made from hollow sections.
- Finishing visible tube edges in a dark, neutral anthracite colour.
- Selecting an insert according to the tube's nominal dimensions and wall thickness, in line with the specification tables below.
Push-in inserts of this type are fitted by pressing the ribbed section into the tube opening until the flange sits flush against its edge. Before ordering, compare the tube dimensions and wall thickness with the catalogue data to ensure a secure fit.

The 40×70 mm tube insert is suitable wherever open tube ends need to be closed during the finishing stage of a structure. It is sold individually, making it easy to order the exact number needed for a project.
