Why do you need a top bee space if there is a large gap at the bottom? Is it just so you can put a feeder on top?
One wonders how one might fit a feed into a bee space.
One might think the question arises because the poster knows not what a bee space is, or is for.
I thought Midland Bee stated the requirements very precisely. I answered your reply with some fairly precise details of the workings of a removable frame hive. Your response - grunt. A grunt as a reply deserves little more comment than 'go and find out', which is where I pointed you toward. I might be good that you understand binary.
