Riga II Optional Upper Shelf
You could use racks or even build your own shelves if you want to. We recommend the Riga Top Shelf. Made from clear twin wall polycarbonate to allow the most light in, these shelves are strong and come with everything you need for attachment. The shelf measures 10" wide x 7' long x one each.
