Description
Rectangular tube insert 10×40 mm, brown

The brown Rectangular tube insert 10×40 mm is a finishing component that closes the open end of a hollow section. It is made of polyethylene, a material commonly used to manufacture inserts and caps that is resistant to moisture and easy to keep clean.
The insert consists of an external part that covers the edge of the tube and an internal part with a core and ribs. The ribs enter the tube and press against its walls, holding the insert in the opening. It is intended for tubes with a nominal size of 10 x 40 mm and a wall thickness within the range stated in the specification.
Applications
- Closing the open ends of rectangular hollow sections.
- Finishing tube structures such as frames, supports and equipment components.
- Colour matching with brown tubes and finishes.
Inserts of this type are pressed into the tube opening until the external part sits flush against its edge. Before ordering, check the nominal tube size and wall thickness, as these determine whether the ribs fit correctly. The product is sold individually.

The internal part determines the insertion depth, while the external part determines the flange thickness. The core and the ribs, which are larger than the core, work together: the ribs deform slightly when pressed into the tube, securing the insert in place. This design is typical of plastic inserts for hollow sections.
