The Exo Terra Screen Cover & Hinged Door Reptile Accessories is a handy way to ensure that your reptiles, feeder insects and other small animals are safely secured. It’s designed for aquariums and glass tanks (sold separately) and is available in multiple sizes to fit most tank sizes. The central hinges let you partially open the enclosure without having to remove any fixtures, so it can reduce stress to your critters and minimize the chance of escape. The strong metal screen provides ventilation and allows UV penetration, too.
