Description
Rectangular tube insert 27×40 mm, grey

The grey Rectangular tube insert is a finishing component that closes the open end of a hollow profile. Made of polyethylene, it is suited to installation companies and workshops needing an attractive, quick-to-fit finish for profile structures.
The internal section of the insert has ribs that press against the profile walls and hold it in the opening. The external flange covers the edge of the profile, providing a neat finish and concealing sharp cut edges.
Applications and selection
- Closing the ends of rectangular profiles in frames, supports and supporting structures
- Covering edges after a profile has been cut to size
- Selection according to the nominal profile size and wall thickness
- The grey colour complements neutral, light-coloured structures
Inserts of this type are pressed into the profile opening until the flange rests against its edge. Before installation, check that the internal dimensions of the profile fall within the range given in the specification, as the ribs' fit depends on the wall thickness.

Installation and use
The insert consists of a flange and an internal section with ribs that slides into the profile. Matching the nominal size and wall thickness of the profile ensures a secure fit. The dimension labels in the specification correspond to the symbols used in the technical documentation, making it easier to check the selection.
