The DIY Screen Door Conversion Kit has everything you need to transform any window, swinging or sliding screen door or fixed screen panel into a dog or cat door. The kit comes with protective screen tape and two sets of lightweight magnets to create a pet door at the bottom of your existing screen door. The deluxe kit includes additional screen, spline and spline tool. It can be installed into your screen frame in 20-30 minutes, making it the easiest magnetic door screen for pets you will ever install. Because the flap is made from the mesh screen already in your door, the flap itself is lightweight and easy to use, making it a great choice for older or more timid pets. The screen door magnets also click the flap back into place with little to no noise, which means you can say goodbye to your pet's noisy door use. Unlike removable screen door curtains, these pet screen doors for dogs and cats stay shut after every use, keeping the outdoors out better than any regular doorway curtains or hanging screens for doors that use enclosures made from adhesive velcro strips. Plus, you won't have to go and spend 100s of dollars on an overpriced screen pet door! The versatile design means that you can customize the height of your pet opeining to be any size from a cat or small dog door, to the largest of dogs door. The width is determined by the width of the frame. It can also be installed in more than just your hingled or sliding door screens. This DIY kit is perfect for your windows, screened rooms, outside cat enclosure and many more uses! Our premium conversion kit includes protective screen tape, heavy duty magnets, and fantastic printed & video instructions that will have you wondering how you ever went without a pet screen door.
