Elite Wall Liner (308) - Works with The 305, 355, 358 and 360 Doors for Easy Installation (Pack of 1)

Very solid

I'm glad I bought this but my wall was definitely thinner than I anticipated. I was worried I would need two but one was plenty. It sticks out about an inch but the exterior cover almost makes up for it. I really don't know how you'd measure the thickness of your walls, but if you know how to do that you'll know exactly how many of these you need.

The item was delivered as expected

Not sure how they meant for this to fit together with the inside door and outside frame? They are the same size, the door flap part and this tunnel. So we duct taped them together and the tape helped it snug in to the outside frame piece. Red Green would be proud of the use of duct tape LOL my cats figured out how to use the door pretty quick and use it a lot to let themselves in and out, esp early morning now INSTEAD of waking me up!

I love the quality and aesthetics of the door. Mounting requirements through a wall should be more clear on website description to inform buyer that they WILL require multiple extensions and order with initial purchase order to avoid delays. The door is easy to use, and my small dog adapted very quickly. Customer support is very responsive. Very good job. Thanks

I can’t say enough bad things about it, or anything good about it. It’s a worthless piece of crap. I never even permanently installed it. It should be sold at a five and dime because it is not worth a dollar. When they say it’s a large, they must be talking rats, because that’s about the size of a large

Great fit for installation of my new cat door

these will lock into place with each other, but not with the inside the house side of the actual cat door. I was told I would need an additional glass door conversion piece. There is a work around. You can use a flat head screw driver to snap off the inner lip of the female side. Doing so means that you can then press this onto the inside the house side of the cat door.
