Energy efficient and tough as nails!

Moved to Nebraska in 2008. House had existing dog door in garage wall as well as door to garage and interior kitchen door. Each one was aluminum frame with dilapidated plastic flaps. It was basically winter INSIDE the house. I bought the small RANGER (Formerly Freedom Pet Pass) wall mount door for the garage wall because it was the only product I could find to fit in the existing hole. It has had five winters use with two rambunctious Westies who each want to be the first one out. Other than having to wash the flaps and frame I have not needed to do a thing to the door. It never freezes open in the winter and it faces the bitter winds we get off the Rockies. Nothing has ever come loose, frayed, sagged,or bagged. The locking panel drops into place and locks with a pin, quite secure. At the time I thought the price was staggering but it really was a smart investment. Am seriously considering replacing current dog door in garage door with RANGER (Formerly Freedom Pet Pass).
