Review on 🐍 Exo Terra Screen Cover for Hinged Door, 15-20 Gallon: Premium Enclosure Accessory for Optimal Ventilation and Secure Habitat by Heather Jordan

Works great! The width easily fits my standard 20 gallon tank. However, it only took me half of this screen to cover a small portion of the tank. It's not long enough to fit in my standard 20 gallon tank. My tank is 12.5 inches wide and 30 inches long. Each half of the screen is 12 inches long and 13 inches wide. So if your tank is over 13 inches wide and 24 inches long, you may have trouble installing it.
