Which pet door do I need to purchase that will use the replacement flap #64027?
Answer by ChewySep 01, 2017
The single replacement flap is compatible with the Classic Pet Door, Deluxe Patio Panel Door, and the Wall Entry Aluminum Pet Door. Item 64027 is the medium size replacement flap in any of these doors.

This seems to be the flap we need. Our door has an inside and outside flap. Are they the same and do we need to order 2 or do we get 2 for this one price.
Answer by ChewyNov 27, 2017
If your current door has two flaps then two should be purchased.

Our flap won't stay shut. Will this sliding door except 2 flaps or should we just order one?
Answer by ChewyMar 01, 2018
This flap works with Classic Pet Door, Deluxe Patio Panel Door and Wall Entry Aluminum Pet Door. If your system uses two flaps, then two should be ordered.

How do I install a pet safe classic large doggie replacement flap?
Answer by ChewyAug 06, 2019
The flap for the Classic Pet Door flap slides into a channel on the top of the frame. To replace the flap, the door must be removed from the installed surface and the screw (either on the right or left side of the top of the frame) must be removed. The old flap can now slide out and the new one will slide in.

Great option

Great option for repair of the door system. Our door has lasted us over 15 years and this is our third replacement flap! Very recommended!

pet door for sliding door

This was exactly what we were looking for! Our other door was so old and warped out of shape, the cold air from outside was gushing inside the house. We have an older model dog door and we were not sure we could get it replaced. Thank you! DeVon

door good, flap not so much

We love our pet safe door. Best thing I’ve ever done for my dogs was give them freedom to come and go. However, the flaps don’t seem to keep up with my dogs. We are replacing flaps about every 6 months. It’s still a great thing for my animals and I will still buy them so they can have that freedom but it’s not economical.

quality question

I hope this one lasts longer than the one I purchased a year ago. The original that came with the door lasted 4 years.

good product but hard to install

The product is fine. I gave only 4 stars because the way the door was made it took hours to get it apart to replace the flap. I believe newer doors have a different mechanism.

Great replacement for old PetSafe door.

I have had the same PetSafe door for 20 years. Depending on the speed of the dogs going in and out the flaps last about 4 years.

Perfect flap replacement

I have a really old pet door and was having trouble finding a correct replacement flap. Chewy had exactly what I needed and even had a video for instruction. It arrived yesterday and is a perfect fit. Thank you Chewy for your wonderful products and service.
