I purchased some used stainless steel kitchen racks on Facebook market place for $10. The measurements are 24 x 48 and 18 x 48 inches. I spay painted them for $10. Now I have a sweet new way to keep my plants off the cold ground during the winter. Also, I can get rid of all my plastic screens that were flimsy and in the way. They are super study and for perfect in a 2 x 4 ft tent. Hope this helps someone!
