So...I bought this to put on the French Doors of my converted garage.
A small part of the top of each part was snapped in transit, so Andersen sent me a replacement.
If you are a kind of 'handy' guy (I'm not at all!) then I'm sure you could figure out how to use these for your French Doors.
They cost me about $500, they are a few months old, never been used, I noticed the snapped parts when I opened the box.
If you're interested, let me know.
For what it's worth, the set that Andersen sent to replace these are fantastic!
Cheers!
