Tank cover ideas

[MikeP]

I currently have eggcrate but it's sitting up above my main lights and partly supports my actinic lights. Every time I need to do anything in the tank I have to move it. I have it in sections but because it's holding the actinic's and is cut so the MH's hang through it's a PITA cause I can't move it all. I would like something I can place on top of the tank rather than on the canopy. I did try eggcrate before but found it blocks to much light. There was a thread a while ago about some sort of mesh with a screen door frame? I searched but couldn't find it. Anyway I'm looking for something that can just sit on the bracing of the tank and therefore be easily moved. I have euro bracing and a center brace so what ever I do will be in 2 sections. The tank is 60 inches long and 24 inches wide but because of the center brace I could have two 24x24ish covers that sit on the glass of the bracing.

Thanks for any idea's
