I will be making a bunch of migratory tops this year. I run both 8 frame and 10 frame boxes. Is there any reason to not use a 10 frame size cover on an 8 frame box? Yes, it will hang over the sides but that should not be a problem as far as I can see. None of the hives will be moved or put on pallets. If I can make only 1 size fits all, it will be a whole lot easier. Any reason not to?
