The Premier Pet View door has everything you need to keep your pet happy. These full glass doors comes with a 10-inch by 17-inch pet door built-in and a slide-in cover to close the opening when needed, keeping unwanted critters out. Not only do they let in the natural light to enhance your entry way, but they are built tough enough to stand up to your active pets. The tear resistant WearTuff screen provides extra durability against active pets and three times stronger than traditional screens. The Reversa Screen design allows for top or bottom ventilation.
