This door is heavy-duty like Fort Knox

I usually don’t write letters about products, but in this case I had to. I have had dog doors for 30 years and have never been so pleased with a product. I recently purchased your large door for my pack and I mean pack, German Shepherd, Rottweiler, Boxer, Labrador, and Boston Terrier. As I live in the country, in Alberta Canada, I have always had problems with weather as in wind and the bugs in the summer and cold as well as wind in the winter with all the previous doors. Not with this one.

My husband has nicknamed the RANGER (Formerly Freedom) door, “Fort Knox”. It is absolutely air tight and looks great. I can’t say enough good things about it and is worth every penny. It is so nice to purchase an item online, get great customer service as well as the product as advertised. I‘ve recommended your door to everyone that I know who needs a pet door.
