Purchased an Armor Flex door. We love it! It has several magnets in each side of the walk through flap. The flap is made up of little sections that freely move on their own, each section capped off with a magnet on each side. When your dog walks through, it is totally flexible and once the dog is through, each little magnet tightly attaches on each side as the flap swings back in place. Very cool! Totally weatherproof!
