Ok, guys, I have to jump in here.
Dario, one question. What makes the seal at the bottom of the screen, as it hits the interior part of the door? Do you velcro across the whole length?
Gene, go to:

(if it doesn't open, go to the main url, then click on woodworking, then magnets, then circular rare earth. I bought some from them and they are the strongest little guys I have ever seen. I took some and merely backed up a rattling magnetic cabinet door catch, and it's so strong the door doesn't rattle anymore!
Put two together and try to pry them apart in a straight motion. Can't be done. You have to 'get under' one of them and slide it off the top and HANG ON!:E
Trust me, they will hold the screen real tight if you don't want velcro.
