Hale is the best!
They make great dog doors, used trouble free by my Brittany and beagle. After 6 years I had to recondition the door and bought replacement flaps and weather stripping, which arrived on time. When I went to recondition the door I was afraid (on Friday afternoon) that I would damage the Hale door, so called to order a replacement. They were very supportive and said it would ship Monday AM. But their door is so well made I didn't have to replace it, just the flaps, so I called Monday to cancel the "rush order" which they did cheerfully! Great product great people.
