Important Note: The Ideal Original replacement flaps come in two different models. You will find either a "square" logo imprint on the center of the flap or a "round" logo imprint. Make sure to check your current flap so you can choose the correct model.
The two models do vary slightly in size

Hints: The "round" logo imprinted flaps began production in early 2007, so chances are that if you purchased your door or patio pet door prior to 2007, you would need the "square logo" imprint flaps.

Your flap will have a round style imprinted logo or an imprint with wording that is Rectangular or Square in arrangement. You will need to select this same style when ordering as there is a slight difference in how flaps will fit. There are not interchangeable. See Example below

Perfect Replacement! March 5, 2013
Reviewer: Kim from Waterford, MI United States  
We love the Ideal doggy door and the replacement flaps are priced well and are a perfect fit. We didn't need a replacement for the first two years since our 2 dogs were older but after the addition of a large crazy puppy who runs 50 mph in/out the door all day, we have replaced the flap annually. Still the best invention ever.
