On your website for M-system MGKWC75AN it specifies a cut out size of 560x490mm. This is not correct. The size should be 560x480mm. This is also specified in the information from Borreti. I suggest you chnage this to avoid any future issues with your clients.
I think that the website should be updated more often. When it states that an item is in stock in Ridderkerk this is not always the case as we found out.
