This was installed on our house but the door opened the wrong way for us. We argued with the builder and finally got the right door unit. It just needs a carpenter with a house for it. Salesman at 84 lumber looked at it and said they sell for $700+. I'd like $200 OBO East Columbus area. This will fit an opening 52-1/2" X 81-1/2" Standard size front door for a house.
