I have an Oceanic Tech tank that has a 2 inch plastic lip all around the periphery of the top of the tank. The egg crate sits there nicely and the mesh wll rest upon the egg crate and be fastened with plastic ties. The egg crate is easy to cut and because of its grid pattern can be cut into many configurations. It can be obtained from any home improvement center. I borrowed this picture from Bluespotjawfishes thread which is where I got the idea.
