Thanks Jeff but I am in the process of converting all my Langs to frames which are across the box rather than along so by mid next Spring I will have split my hive to two and have no standard frames at all.

I have two more boxs with ledges to take the frames X wise and I am in the process of making the frames to fit. They are just so easy for me to handle.
Ah the penny has dropped. Just visualized your 2 or 3 frames on top of each other. You could slide them in and out from the side on couple of angle iron runners. Each would have their own runners of course. I could utilize the standard Lang frames I am getting rid of.
Or run 2 or 3 end to end. Maybe the bees might have trouble adapting to single frames end to end.
EDIT: Off course there would have to be pathways for the bees to move
between frames.
Thanks Jeff,
