Description
Rectangular tube insert 35×45 mm, grey

The grey Rectangular tube insert 35×45 mm is a push-fit finishing component that closes the open end of a hollow section. Inserts of this type provide a neat finish to the tube edge and help prevent dirt from entering.
The insert consists of a flat flange that covers the tube edge and an internal section with ribs. The ribs conform to the tube walls and hold the insert in place once pushed in. The design accommodates a wide range of wall thicknesses, making one model suitable for different tubes with nominal dimensions of 35×45 mm.
Applications and selection
- Closing the ends of rectangular tubes in steel and aluminium structures
- Finishing frames and support structures where the open tube end is visible
- Selection based on the nominal tube dimensions and wall thickness, which determines the grip of the ribs
- Neutral grey colour complements steel and galvanised tubes
The insert is made of polyethylene, a material commonly used for this type of product. To install, push the ribbed section into the open end of the tube until the flange rests against its edge. For installation companies, it is a simple, quick-to-fit component that completes hollow-section structures.

The nominal tube dimensions and wall thickness are key factors when selecting an insert. The external and internal section heights, along with the core and rib dimensions provided in the specifications, allow you to check the fit for a particular tube before installation.
