Duraflex Heavy Duty Dog Door - Large

This door is great. My old one left a lot to be desired. It never sealed along the sides very well and would blow open all the time. This one has already helped keep the house warmer during the couple Weeks I've had it installed. The only drawback is that it isn't clear like the old door, but that does help keep my Malinois from crashing through the door, haha!
