Since I live close to this company, I went in person to order my doors. They explained the various intricacies of the doors which helped me make the proper choices. I walked out of there very happy with my two doors. Thank you.

Item came in as expected and matched the description well. The door, louvers, and screen are well built and appear to be able to stand the test of time for quite a while.
