External tube end cap for round tube Ø 21 mm, white

The white round external tube end cap fits over the end of a round tube with a diameter of Ø 21 mm. It closes the open tube end and gives it a neat, uniform finish.

External tube end caps of this type are used wherever an open tube end needs to be protected against dirt and debris entering the tube while maintaining a tidy appearance. For installation companies, this simple finishing component helps complete the assembly of round tube structures.

Selection and application

When selecting an end cap, the most important measurement is its internal diameter, which should match the external diameter of the tube. The internal depth determines how far the cap slides onto the tube, while the overall height determines how far it extends beyond the tube end.

External tube end caps of this kind are pushed onto a prepared, clean and square-cut tube end. Before fitting, check that the tube edge has no burrs that could make the cap difficult to fit or spoil the appearance of the finish.

The white finish is suitable where tube ends need to blend into a light-coloured background, such as on frames and lightweight structures. The cap's solid, closed top covers the tube opening and gives the whole connection a tidy appearance.
