Description
Rectangular tube insert 20×30 mm, grey

The grey Rectangular tube insert 20×30 mm is a practical finishing component for businesses that protect the open ends of hollow sections in steel structures, frames, supports and bases.
Made of polyethylene, the insert consists of a flat outer section that covers the edge of the tube and a recessed inner section with fins. The fins press against the tube walls and hold the insert in place, while the neat closure improves the appearance of the finished structure.
The insert is designed for tubes with different wall thicknesses, allowing one size to fit several variants of 20×30 mm tube. Polyethylene is a material commonly used for injection-moulded products such as inserts. It does not corrode and requires no additional painting.

Applications
- protecting the ends of 20×30 mm rectangular tubes against dirt and contaminants
- providing a neat finish for frames, supports and structures made from hollow sections
- covering the sharp edges of the open tube end
Selection and installation
When selecting an insert, match it to the nominal tube size and wall thickness. Fit the insert into the tube opening by pressing in the inner section until the outer section rests against the tube edge.
