Description
Rectangular tube insert 20×60 mm, black

The black Rectangular tube insert 20×60 mm is used to close the open ends of rectangular tubes. It protects the tube opening and gives the end of the structure a neat, uniform appearance.
The insert consists of a flat flange that covers the edge of the tube and an internal section with transverse ribs. When pushed into the tube, the ribs conform to its interior and hold the insert in place. Installation simply involves pushing the insert into the tube opening.
Applications and selection
- protecting the ends of rectangular tubes in support structures, frames and frameworks
- suitable for tubes with different wall thicknesses – the insert accommodates a wide range of thicknesses
- finishing visible tube ends in a uniform black colour

Material and construction
The insert is made of polyethylene, a material commonly used for finishing components. It is lightweight and sold individually, allowing you to purchase exactly the quantity needed for the project.
The external flange and ribbed internal section allow the insert to fit a tube with nominal dimensions of 20×60 mm and various wall thicknesses, while the push-in stem sits securely inside the tube. The insert is well suited to protecting tube ends in frameworks and support structures.
