Description
Rectangular tube insert 20×40 mm, brown

The brown Rectangular tube insert for 20×40 mm profiles closes the open end of a hollow profile, giving it a neat, finished appearance. It is made of polyethylene, and its flat head covers the edge of the profile once installed.
The internal section of the insert has several ribs that press against the profile walls when pushed in, holding the insert in place. The ribbed design is intended for profiles with a wall thickness of 1.0 to 3.0 mm, making it easier to fit profiles with slightly different dimensions.
Applications
- closing the ends of steel and aluminium profiles with a 20×40 mm rectangular cross-section
- finishing support structures, frames, railings, fences and stands
- neatly finishing visible profile ends
- colour matching with brown structural components
Polyethylene inserts are commonly used to finish hollow profiles and are installed by pressing them into the profile opening. Polyethylene is a lightweight, moisture-resistant material, making inserts of this type suitable for both indoor and outdoor use.

The insert consists of two parts: an external head that covers the edge of the profile and an internal ribbed shank that fits inside it. This design ensures that the insert is held securely in place after installation and that the head sits against the end of the profile.
