1. Made with premium materials and lifetime replacement: The magnetic mesh door curtain uses high-density, heavy-duty materials and a durable, sturdy mesh, making it perfect for pet screen doors and high-traffic doorways. It lets in fresh air and light while keeping out annoying irritants. 2. Closes smoothly and is easy to open with one hand: Sewn-in magnets. The center seam of the screen door is strategically lined with powerful magnetic cubes and strips that allow the door to open easily, quietly, and close smoothly. It allows dogs or cats to come and go freely, and you won't have to get up and open the door every time. Therefore, it works as both a screen door and a dog door. 3. Avoid the hassle of constantly opening the door for your dogs to go out. Our screen door for dogs allows your furry friends to come and go as they please; it also works for cats.
