  1. Aluminum Pet Door Insert 4 Star Review

    Posted by on 27th Mar 2019

    This was very easy to install. Since older houses rarely are perfectly square it took a bit of thicker weatherstripping to shore up the edges so there was a tight seal on the sides. It would be nice if there was an added piece on the side like a channel from top to bottom where the patio door could slide into and have a latch to hook. This would make it perfect. There is a lock included. I put this at the top and ordered another one for the bottom. This is necessary to pull the door in tight enough to seal next to the side of the pet door insert. I will have a latch also on the outside to close it tight after exiting. I ordered this door through Home Depot and ordered the extra lock and latch from Ideal Pet.
