Does the MaxxAir vent covers have enough room for the vents to open all the way?

I installed mine over the bathroom vent and it has enough room to open up all the way. It started raining so I didn't get the other vent cover in yet. BTW We had almost horizontal rain a few days ago coming from the north. The back end of my 180R faced the north, and my bathroom vent was wide open. No rain come into the trailer.

Thanks MT.  I was about sold on them and this information finalizes it.  I like the installation on the MaxxAir rather than on those models that require taking a screw out of the vent frame.  I don't want to break the Dicor seal even though it can be replaced.
