how to put screens on french doors that swing in?

Answer 1

There's a type of screen you can buy at Home Depot type stores that mounts to the side of the door opening and you pull it out and clip it on the other side of the opening... like a roll-up window shade only sideways and made of screening.
When not in use, just roll it back into it's mounted tube-like area......neat idea, don't know the manufacturer but I would think any place that sells french doors would have heard of it.

Answer 2

With screws. Lag bolts for big screens.
