The first doggie door that I purchased was close to 18 years ago and it was a Plexidor. This purchase was to replace that door because it was an easy install in the existing "human" door that already had the opening cut into it. We replaced it with the same Plexidor because of the quality and longevity of this product. Great, reliable product and couldn't be happier!!
The Best Pet DoorMost pets hate flap doors! PlexiDor Pet Doors are long-lasting and beloved alternatives.
They have hinges, like a door, so there's no loud flap slap or flexible materials. They lock easily, and most models come with a steel security plate for additional security when you are away.
