The replacement door kit is great!
After about 8-9 years, my outside door flap started to crack, so I bought the replacement flap kit. I am not at all handy, but it was very easy to do. My original door was totally great, easy for my dog to use, and very weather proof. the replacement looks every bit as good. You can also securely close the inside door at night or when you are out of town, with a heavy duty plastic insert that locks into place. Hale is a really good company, and they make a really good product.
