Description
Rectangular tube insert 30×50 mm, white

The Rectangular tube insert provides a neat finish for open ends of rectangular profiles. Pressed into the profile, it gives the end a finished appearance and covers the cut edge. The white version complements light-coloured structural components.
The internal part of the insert has ribs that press against the inner walls of the profile and hold it in place. The external flange covers the edge of the profile. The wide wall thickness range allows the same type of insert to be used with several profile variants of the same nominal size, simplifying procurement for projects.
Applications
- Finishing profile ends in frames, structures and supports
- Closing the open end of a profile after cutting it to length
- Providing a neat finish to visible structural components
- Quickly completing the finish during installation – the item is sold individually
Polyethylene inserts are a commonly used solution for protecting profile ends. The material is lightweight, and the compact size of the item makes it easy to store and transport to site. Before purchasing, measure the internal cross-section of the profile and check its wall thickness to select an insert with suitable core and rib dimensions, as specified below.

Selecting the right insert for the profile
- The height of the external and internal parts affects how deeply the insert sits in the profile
- The core and rib dimensions determine the fit inside the profile
- The profile wall thickness determines the pressure exerted by the ribs
