Description
Rectangular tube insert 40×120 mm, grey, wall thickness 1.7–3.0 mm

The grey Rectangular tube insert is a finishing component that closes the open end of a hollow section. It is designed for tubes with nominal dimensions of 40×120 mm and fits wall thicknesses of 1.7–3.0 mm, allowing one size to accommodate different wall thicknesses of this tube size.
The insert is made of polyethylene. It consists of a flat, rounded outer flange that covers the edge of the tube and an internal section with transverse ribs that is pressed into the tube opening. This design is typical of push-fit inserts and provides a neat, even finish to the tube end.
Applications
- Closing the ends of rectangular tubes in structures and frames
- Protecting against sharp edges after cutting the tube
- Reducing the ingress of dirt into the tube
- Providing a neat finish to visible ends of hollow sections

Selecting the right insert
Push-fit inserts are selected according to the external dimensions and wall thickness of the tube, as the wall thickness determines the size of the opening in which the ribs are seated. Before ordering, measure the tube and check that its wall thickness falls within the range stated in the specification.
The product is sold as a single piece, allowing you to order exactly as many inserts as there are open tube ends in your project.
