Description
Rectangular tube insert 30×40 mm, white

The white Rectangular tube insert 30×40 mm provides a neat finish for open ends of hollow sections. It is made from polyethylene and sold individually, making it easy to order the exact quantity required for a job.
The internal section of the insert has ribs that are pressed into the tube opening. It accommodates different tube wall thicknesses, allowing the same insert to be used in tubes with slightly different specifications. The external flange covers and protects the tube edge and provides a neat finish.
Applications
- Finishing the ends of 30×40 mm rectangular steel and aluminium tubes in support structures, frames and technical furniture
- Protecting the opening against dirt and users against sharp tube edges
- Providing a light-coloured finish for visible tube ends in installations and enclosures

Before purchase, check the nominal tube dimensions and wall thickness against the specification. When correctly selected, the insert's ribs grip the inside of the tube and hold it securely, while the flange sits against the edge. Polyethylene is a lightweight plastic commonly used for finishing components, so the insert adds almost no load to the structure.
