since my modules can be split ie. the keystone jacks can be separated from the modular. Is there anything made by MK to which the keystone jacks can be clipped onto. Even if it is a faceplate made with shutter doors already in place to which the keystones can be clipped into the back of
Who is the manufacturer of the ones you currently have? They may have euro sized modules you could clip your keystone jacks into.
Alternatively in the picture below it looks like the keystone jacks on the MK are clipped in. I doubt anywhere sell the euro module without the keystone jacks but you could find the cheapest euro module they do, unclip the keystone jack it comes with and clip in yours. Go to a shop and ask to see one to make sure it can be unclipped.
