Description
Rectangular tube insert 40×70 mm, grey

The grey Rectangular tube insert 40×70 mm is a finishing component for closing the open ends of tubes and hollow sections. A single model fits profiles of the same nominal size with different wall thicknesses, reducing the number of variants needed for a job.
The insert is made of polyethylene. Its internal section has fins that press against the profile walls when inserted, holding the component in place. The flat external flange covers the edge of the profile, creating a neat, even finish.
Applications
- closing the ends of rectangular profiles in structures and products made from tubes and hollow sections
- finishing frames, support structures and equipment made from profiles
- protecting the inside of the profile from dirt
- covering the edge of a profile after cutting
The grey colour of the insert complements structures in neutral colours. The product is sold individually, making it easy to select the exact number of components needed for a job.

When selecting an insert, it is important to match the nominal profile dimensions and the internal cross-section against which the fins press. The external section of the insert remains outside the profile as a flange, while the internal section enters the profile and presses against its walls. The exact dimensions are listed in the specification below.
