Review on 🐾 Endura Flap Pet Door: Extra Insulated, Energy Efficient, and Durable Doggie and Cat Door for Small, Medium, Large, XL Pets. Available in Black, Tan, and White Frame Options with Locking Cover by Christine Allen

Fairly easy to fit, has no gaps and comes with a gasket to close the door cut out. Sturdy flap that seems to block all external elements. The open screw holes on the dog door had white plugs, but they were too big and didn't fit at all. I couldn't even hit her. It took 4-5 weeks for my 25-35 lb dogs to walk through the door on their own. The magnetic closure is very strong and makes a loud noise when the flap closes. That was the main reason my dogs didn't want to use it. I temporarily removed the magnetic bar to reduce this noise and make the lid easier to open while teaching my dogs to use the dog door. Removing this bar will leave a 1 to 2 inch open gap outside under the door flap, so you don't want to leave it. After they got the hang of the dog flap, I readjusted the rod and they eventually warmed up to a loud clang. Noise when closing the flap.
