Walk through hands-free - Under the door towel, it is equipped with some counterweight strips, sewn into the reinforced edges, so that it can open and close automatically immediately. Children and pets can also easily enter and exit the house. Correct use - Make sure to flatten the product before installation to avoid creases, otherwise there will be an error of 2-3 cm after installation. It is correct to measure the door size before purchase. Hang the screen straight and do not overtighten it before gluing it, so that the magnets can catch each other when the towel is closed. Pet-friendly - These magnetic screen doors can avoid noise and be quieter. Size selection: door hanger width ≥ (door frame width + 8 cm), door hanger length ≥ (door frame length + 6 cm). Easy installation - There is a long, sticky Velcro strap with the towel. You can attach the towel to the door frame without tools. For customers who are sensitive to odors, you can wash the product with water and dry it naturally to reduce the odor. Hand wash only, do not machine wash, do not tumble dry, do not wring out the net, etc. as it will deform it. Keeps insects away - The net is made of high-density and antioxidant material, which is strong and durable. Even the smallest insects and mosquitoes have no chance of getting in, while letting in fresh air.
