PLEASE NOTE: This is the "old version" of the screen top. It has tabs on the sides to lock it down, instead of half circle closures.
It will still fit between the "old" and "new" style Exo Terra enclosures. However if you have an animal that could push on the screen top (like a snake) it won't stay locked down if you have the wrong style closure.
Please check your enclosure to see which one you need before ordering.
