I bought this to have installed in a screened wall of out patio. It worked so well that the people who installed the wall contacted me to find out more about it.Much better than my last pet door. You won't be disappointed with the quality. Closes well. The cover to shut it would be my only concern. Not great but I don't need it for this door.Four years ago my Pride dog door finally gave up, it was 35 years old and I could not find new or parts I live in the county, keep livestock and have three large dogs the backporch/canning kitchen so they can keep warm.Since then I went through two other dog doors both costing around two hundred each. They were both double door insulated and neither was very good. You could see out either side and one of them light under the door,On one, both doors warped and would not seal, the second door I could not keep the doors from falling off. Had to dismantle and reinstall the door system each time one or the other door fell off.True three large dogs can give a door a lot of abuse when all three bust through the door at high speed because they heard something outside.I was so excited to find that someone picked up and started making pride doors again. This one is working great even though we have three dogs over 100 pounds each using the door regularlyand I am happy again.I bought this to replace one I had for at least 15 years. However, it did not fit into the opening. This was the same model # as the prior one but I had to modify the opening. I realize that changes are made over the years so understand. It is framed into my screen pool enclosure so it is out in the weather. The panel that you use to keep it closed is not weather proof. I don't currently have a dog so I left that in to keep out raccoons. I'm going to have to find something else to put in the slots as it deteriorated quickly. With that said, the prior one lasted many years but I thought it was over priced for what I got but I could not find anything else that was close enough to fit the opening.The door we installed lasted 12 years. It seals perfectly and it doesn’t close hard on the dog when they come in and out. We were so glad we could order the same door.It looks great , it fit perfect, best of all , my dog LOVES IT ! Thanks for making a great product!Worked as intendedwork great
