PlexiDor Heavy Duty Pet Door for Dogs & Cats - Large Wall Mounted Dog Door with Lock & Key, Bronze - Perfect for Indoor/Outdoor Access, Home & Patio Use

Love this door, it is really nice quality. My handy man said it was a unique install, but he watched the online video and it was easy. He has installed hundreds, he said this is the nicest one he has ever seen! I thought the way it was built would hold up to 3 big dogs and extreme temperatures. Now its getting my 3 chow dogs trained to use it, They are doing really well, with me opening the one door and they follow the leader through the door. My old guy was the one I thought would have a rough time, that is why I choose this design since the outside is 2" lower, I though it would be easier for him to use. For right now used a teak door mat angled outside the door as the ramp. It is pretty pricey, but I have seen some other door that are all plastic and they still run a couple hundred dollars. This one is worth the money, to know it can be securely locked and closed if need be.
