Description
Rectangular tube insert 40×50 mm, grey

The grey Rectangular tube insert 40×50 mm provides a neat finish for the open ends of hollow sections. It is made of polyethylene and sold individually in units of 1 piece, making it easy to order the precise quantity required for a project.
The internal section of the insert has fins that hold it in place when pressed into the tube. The external flange covers the edge of the tube, giving the closed end a neat appearance and concealing the opening.
Choosing the right tube
- Designed for rectangular tubes with nominal dimensions of 40×50 mm
- Suitable for tube wall thicknesses from 1.5 to 3.0 mm, allowing use with different tube variants
- The grey colour allows the insert to match light-coloured structural elements

Inserts of this type are commonly used in hollow-section structures such as frames, bases, railings and support elements. Installation involves pressing the internal section into the tube opening until the flange sits against its edge.
Polyethylene is a plastic commonly used to manufacture finishing components. The insert is classified as a small parcel, and its unit weight is given in the specification below.
