Description
Square tube insert 30×30 mm, grey

The grey Square tube insert 30×30 mm is a simple finishing component that closes the open end of a hollow section. It is made of polyethylene and sold individually in quantities of 1 piece.
Inserts of this type are used to protect the ends of square tubes and sections from dirt and prevent debris from entering. The closed end looks neater and the sharp cut edge is no longer exposed. The outer flange covers the edge of the tube, while the ribbed inner part fits inside it.
Tube compatibility
- For square tubes with a nominal size of 30 x 30 mm
- Select according to tube wall thickness — see the range in the dimensions table
- Ribs on the inner part hold the insert in the tube
- The heights of the outer and inner parts help assess the fit
For installation companies, this is a standard small finishing component for structures made from hollow sections, such as frames, bases and supports. Before ordering a larger quantity, check the actual dimensions and wall thickness of the tube used, as these determine whether the insert fits correctly.

The insert's dimensional markings include the height of the outer part C, the height of the inner part H and the tube wall thickness R for which the insert is selected. Inserts for hollow sections are usually fitted by pressing them gently into place until the flange sits against the edge of the tube.
