Query: great solution!

We were looking at having to put a hole in the wall until we found this solution for the patio door! It was easy to install and works great. We watched the installation video on the website as we installed it and it made it even easier. The only con to it is that we don't have a lot of room to exit the patio door ourselves now, but I am sure this will depend on your size of patio door.
