Description
Square tube insert 40×40 mm, black, wall thickness 1.2–3.0 mm

The Square tube insert 40×40 mm closes the open end of a tube or hollow section, providing a neat finish and limiting the ingress of dirt into the profile.
The product is intended for profiles with a wall thickness within the range specified. The push-in internal part with ribs fits into the profile opening, while the external head covers its edge. Such inserts are commonly used to finish the ends of steel and aluminium profiles.
Applications
- Finishing the ends of 40×40 mm square profiles in support structures and frames
- Protecting open profile ends against dirt
- Providing a neat finish to profile ends
Polyethylene is a material commonly used to manufacture profile inserts. The insert is pushed into the end of the profile, and the ribs on the internal part hold it in place.

When selecting an insert, it is essential to match it to the nominal profile size and wall thickness. For installation companies, it is a simple finishing component that allows profile ends in support structures and frames to be closed quickly.
