Description
Square tube insert 120×120 mm, brown

The brown Square tube insert 120×120 mm is a finishing component that closes the open end of a hollow tube. For installation companies, it provides a neat and attractive finish for support structures, fences, railings and frames made from square tubes.
The insert is made of polyethylene, a material widely used for finishing products due to its moisture resistance and ease of moulding. The internal section has ribs that grip the tube walls and hold the insert in place, while the external flange covers the tube edge and conceals its cross-section.
The product accommodates a wide range of tube wall thicknesses, allowing one variant to be used with several versions of 120 x 120 mm tube. The brown colour complements dark-coloured structures, and the dimensions of the individual parts of the insert are given in the specification below.

Applications
- Closing open ends of square tubes in steel and aluminium structures
- Finishing fences, railings and frames
- Neatly concealing the tube cross-section
- Closing tube openings in externally visible structural components
Inserts should be selected according to the nominal tube size and wall thickness. The product is sold individually, and its low unit weight means it is classified as a small parcel.
