ᐅ Naber wall box for 540mm thick wall

Hello everyone,

I recently ordered the Naber E-Jal Col Thermobox 150mm (6 inches) wall box for our range hood.
The package arrived yesterday, and only then did I realize that it is suitable for a total width of up to 500mm (20 inches) max.

I have already seen that there are telescopic ducts with a 150mm (6 inches) diameter. Does anyone know if you can use just any type for this?
I would like to hear about your experiences on this topic.

Thank you very much and best regards,
Julian

Oh my. Where do you live that 500mm (20 inches) isn’t enough, or what is the question?

The question is whether I can use any telescopic pipe with a 150 mm (6 inches) diameter, or if it has to be one from Naber.

This probably doesn’t matter, but it is always better to stay within the same system. The systems are designed to work together. Otherwise, everyone tends to deny responsibility.
