This online - only item is the perfect solution if you need a replacement flap for your dog or cat's door. The Classic Replacement Flap is compatible with your existing Classic Pet Door, Deluxe Patio Panel Pet Door, the old model of Wall Entry Aluminum Pet Door™, and the old - model Larson Storm Door with Classic Pet Door. It has a magnet at the bottom to keep the door closed when your pets aren't moving in and out. Key features include a soft, tinted vinyl flap with magnetic closure. Replacing it is a simple DIY project. It comes in four sizes: small, medium, large, and extra - large. Note that this replacement flap only works with the old model of the Wall Entry Aluminum Pet Door™. To tell the old and new models apart, check these points: the new model has screws on the top of the frame, the inner white frame of the new model is flat and nearly flush with the brown frame, and the bottom of the flap on the new model has a thin, smooth black weather strip. Sizes available are Small (13 x 18cm), Medium (20.3 x 28cm), and Large (25.4 x 38cm).









Using this replacement flap is super easy. First, make sure you have the right model of the pet door. If you have the Wall Entry Aluminum Pet Door™, double - check it's the old model. Then, simply remove the old flap and put in the new one. It's a quick DIY job. As for maintenance, clean the flap regularly with a mild soap and water to keep it in good condition. When your pet isn't using the door, the magnetic closure will help keep it shut, which is great for energy efficiency. Just be careful not to force the flap open or shut too hard, as this could damage the magnetic seal. Also, check the flap periodically for any signs of wear and tear, and replace it if necessary.
