Dear Sir, Madam,
I would like to know the exact dimensions of this product, it says 204x65 but clearly the 2 hose nozzles are slightly bigger than the pipe in the middle, could you please give me the exact dimensions of the different parts of this product ? The space I have for my installation is really small so it is a question of millimetres for me.
Thank you
