You could get a good size plastic bin with a lid to put the frames in, you would want it big enough in depth and length for the frames and be able to put the lid on. I have a board that is bigger that a super that I put on a Dollie, then an empty super to hold the frames, and another board to go on top of the supers. Part of the time I use a telescoping top for the top. The bees aren't to bad in the spring but can bee in the summer or fall to keep off the frames. Good luck
