Description
Rectangular tube insert 50×100 mm, black, 2.0–4.0 mm wall thickness

The Rectangular tube insert 50×100 mm is a finishing component for closing the open ends of hollow sections. It consists of a flat external flange and an internal part with ribs that fits inside the profile.
Application and selection
Inserts of this type are used to protect the ends of steel and aluminium profiles from dirt and moisture and to give the structure a neat finish. When selecting an insert, check the nominal profile dimensions and actual wall thickness, as these determine the fit of the internal part. This is a solution for installation companies and structural fabricators who need a simple, consistent way to close rectangular profiles.
Construction and installation
The ribs on the internal part press against the profile walls and hold the insert in place, while the external flange covers the edge of the profile to provide an even, closed finish. Installation involves pressing the insert into the open end of the profile. The black colour complements dark-coloured structures.
- Closing the open ends of rectangular profiles in steel and aluminium structures
