Description
Rectangular tube insert 20×30 mm, brown

The brown Rectangular tube insert 20×30 mm is a finishing component that closes the open end of a hollow profile. It neatly covers the edge of the profile and prevents dirt from entering.
The internal section of the insert has ribs that are pressed into the profile, while the flat external flange covers its edge. Inserts of this type are fitted by simply pressing them into the open end of the profile. Polyethylene is commonly used for finishing components for hollow profiles.
Applications and selection
- closing the ends of rectangular profiles of this size
- finishing frames, supports, bases and railings made from hollow profiles
- the brown colour allows the insert to be matched to structures in similar colours
- sold as a single piece, allowing you to order exactly the number of inserts needed
When selecting an insert, check the external dimensions and wall thickness of the profile against the specification. Press-in inserts should be selected so that the ribs fit snugly inside the profile and the flange sits flush against its edge. The dimensions of the external and internal sections, core and ribs are given below, together with the labels from the technical drawing.

The insert for hollow profiles protects profile ends from moisture, dust and small particles of dirt, while giving the structure a neat, finished appearance. The smooth, flat surface of the flange sits neatly against the edge of the profile.
