Definately Tape Together
By Jack on Mar 17, 2021
If you need these to extend the tunnel through a wall, like I did, make sure to tape them on the outside like the instructions say. The plastic is fairly thin and gaps will appear at the joints as it flexes. I also made sure the bottom was supported by putting wood shims under it. I didn't want the floor to sag when the cat moved through it. Suggestion for filling the gap between these extensions and the outside trim piece: Use foam tape applied either on the outside of the extender (it it is accessible) or in the inside of the trim piece . Don't get me wrong, I like the product. The pieces fit together nicely and it was the perfect way to get the door installed in our wall.

Great Door
By Chewey on Aug 11, 2018
I love the SureFlap Door. It has helped train our puppies to use the potty outside. The only reason I rated it a 4 was because there is some space between the frame and the door itself. I worry about the winter time and heat escaping and cold weather entering.
