Description
Rectangular tube insert 25×80 mm, grey

The grey Rectangular tube insert 25 x 80 mm is a practical finishing component for protecting the open ends of hollow sections. It is made of polyethylene, a material commonly used to manufacture inserts that does not corrode and withstands everyday use.
Inserts of this type are pushed into the open end of the tube. The external flange covers the edge of the tube and gives the end a neat, closed appearance, while the fins on the inside press against the tube walls and hold the insert in place. This prevents dirt from entering the tube and covers sharp cut edges.
The fins accommodate small variations in the internal dimensions of the tube, so the same insert fits tubes with different wall thicknesses within the range specified. When selecting an insert, compare the nominal tube size and wall thickness with the details in the tables below.
Applications
- Protecting the open ends of rectangular hollow sections
- Finishing structures, frames and equipment made from hollow sections
- Protecting the inside of the tube from dust and dirt
- Covering sharp edges left after cutting the tube
- Neutral grey colour complements many structures
