Upgraded Magnets for a Better Seal - Unlike other balcony door fly screens that only have 26 small magnetic strips, our fly screen door has 34 longer and stronger magnets that run the entire length of the screen, making the fly screen door close seamlessly and quickly. Fabric Upgrade and More Durable - The magnetic fly screen door is made of durable polyester fiber and reinforced edges. The polyester magnetic mesh has good abrasion resistance and can withstand continuous wear and tear, providing better security and a longer service life. The mosquito net door brings more life to your life. How practical. Child and Pet Friendly - With the self-closing function, the magnetic mosquito screen door allows children and small dogs or cats to come and go freely. Perfect for letting in fresh air while keeping out annoying outdoor irritants. Easy to Install and Remove - The fly screen door without drilling is very easy to install and remove. Includes an illustrated installation guide, a roll of adhesive tape, and a pack of thumbtacks. Simply use the included adhesive tape to attach it to the door frame. Additional pins increase security and strength. Size Note: Please measure your door size before purchasing, including the width and height of the inner door frame. Add 4 cm to the width of the interior door and 2 cm to the height of the interior door, and then select the correct size. Choose the correct size that is closest to (but not smaller than) the inner frame.
