High quality: The door net has outstanding magnetic strength and closes automatically in one second, quietly and tightly. The wider Velcro at the top and the strong mesh of the net give it a greater load capacity; durable and strong for many years of use. Mosquito and insect resistant, safe for pets and children, perfect for patios, balconies, RVs and more. Easy to install and remove: No drilling required, quick installation in minutes. The Velcro is suitable for solid, smooth door frames, except for painted walls (which are fragile and can crack). Comes with nails for uneven wooden door frames. The door curtain is easy to remove and in most cases leaves no traces. Full range of sizes: We have hundreds of sizes to choose from. Some sizes are shipped via international courier, which takes longer. Please check the estimated delivery time on the page before placing your order to ensure you can wait that long. The item's dimensions include Velcro for the edge, 4 cm wide for the top Velcro and 2 cm wide for the left and right Velcro. To choose the right size: the curtain is 140 cm wide and 220 cm high. Measure the inside width and height of your door frame and then add at least 5 cm to both measurements. The inside width of your door frame should not exceed 135 cm and the height should not exceed 215 cm. It is recommended to buy a larger curtain rather than a smaller one, as long as it does not exceed the outside dimensions of your door frame.
