Description
Rectangular tube insert 40×100 mm, black, wall thickness 1.5–4.0 mm

The black Rectangular tube insert 40×100 mm is designed to close the ends of profiles with a wall thickness of 1.5 to 4.0 mm. Thanks to the wide wall thickness range, one insert fits different profiles with the same nominal dimensions, making it easier to assemble orders for installation teams.
The insert consists of a flat flange that covers the edge of the profile and an insert section with ribs. The ribs adapt to the inside of the profile and hold the insert in place once pressed in. The smooth black flange provides a neat finish to the end of the profile.
Applications and selection
- Protecting the open ends of rectangular profiles against the ingress of dirt
- Providing a neat finish to profile ends in structures, frames and supports
- Selection according to the nominal profile dimensions and wall thickness
Material
The insert is made of polyethylene, a plastic commonly used for profile finishing components. The black colour complements dark profiles and structures.

When selecting an insert, the nominal profile dimensions and wall thickness are essential, as the latter determines how firmly the ribs press against the inner edges. Once pressed in, a correctly selected insert securely closes the end of the profile.
