We attached this product to a canopy carport. We use it to play cards in and the screen is great to keep bugs out.
See the picture for an example of how we mounted the screen to our garage door. We mounted it on the flashing around the door because it allowed the screen to fit almost perfectly (its just a little too long for my door, but I am very happy with it. There are 5 strong velcro strips that you screw into the top to hold the screen up. It then comes with 10 velcro pads that can be attached to the sides to hold them in place ... oddly they send both pieces of the velcro (hook side and the fuzzy side) when the side of screen door acts as the "fuzzy" side. So originally we were just going to discard the fuzzy side ...
It does what we expected. We are happy!
Keeps the chickens out, but the fog has no issues with coming to visit
Put it ip a couple months ago. Velcro didn't stick well to the wood, but the tacks that were provided helped keep it secured. Would definitely buy another one..
