Realized my patio door was not the kind this was designed to fit. The dog door is made for patio doors that are flat surface to flat surface. Mine has more like a slotting fit, so the drill in locks to keep the door closed were not usable. There are also a lot of voids that I filled with a ton of backer rod and stuff like that to make it sort of air tight. The flap itself is great and seals shut well, so after all the creativity required to get the door installed, it works well.
