Steven -

That "extra" space is there for a reason. It allows you room to move frames apart so when you lift a frame of comb out you don't roll all the bees. Simply split the difference and center all your frames in the chamber and you'll have a little extra space on each side. Not a problem.

Thank you for the answer Barry.

Some people add a frame,they say it's better for keeping brood warm in winter and keep SHBs out. Once you get the first frame out on end you can slide the rest over before pulling them out and they don't roll the bees. Tight frames don't hurt.
