Rated 3.0 out of 5.0 by redgarnet54 Good concept for placement within wall opening, but not adjustable for depth, recommend with reservations.
We bought this in addition to the actual dog door kit. Since we were installing through an exterior wall, there is a need for some type of coverage to the exposed internal portion of the wall as the door itself and the exterior frame are not thick enough to cover the "raw" interior of the wall. That being said, the wall we inserted the dog door through is not your traditional concrete block wall which I would bet to say is why this tunnel is as deep as it is. We have a foam-walled sunroom which is about 1" thinner than the traditional block wall, so when we attempted to install the tunnel within the wall opening, it was too deep to be able to attach the door appropriately to the wall itself. Therefore, we were unable to use it. I was hoping this tunnel was adjustable as it looked from the picture that one side slid over the other, but it is only one solid piece of plastic. It would have been too much of a hassle to try to return it.
Bottom line: I recommend with reservations. If you are installing the door through a traditional exterior wall, this might work for you. Otherwise, measure and cut your opening so both sides are level with each other. Even a slight 1/16" drop from one side to the other will affect how this tunnel works.

Rated 4.0 out of 5.0 by TFA I had to buy extra tunnel.
I ordered PX1 and 1 tunnel attachment. I am ordering 2nd tunnel attachment because my wall has bricks and the depth is 10 inches brick wall and this tunnel covers 5 Inch depth. By ordering 2 tunnel, it give me 10 inch depth needed.

Although we had to build in an extra support due to siding, the wall tunnel made this process 1000 times easier.
