Review on 🐶 13.75" x 23.75" XL Dog Door Flap - Compatible with PetSafe Freedom Doggie Doors PAC 11-11040 - Flexible Weather-Resistant Material - Replacement Flap for Extra Large Doggie Doors by Nicole Davis

This is superior to the Pet Safe PAC 11-11040 replacement sheet. It's slightly thicker, the perfect length - doesn't require much adjustment, and is slightly wider. I've had several spare Pet Safe Flats and they were never wide enough. It fits perfectly. I was so disappointed with the Pet Safe Panels. I would set it perfectly and they would slip off after a few uses. And even with proper adjustment on the sides, there was still a small gap. I highly recommend this product. And it costs less. I even tried 2 Pet Safe valves. It was worse and the price is just ridiculous.
