Dummy boards

[Aggravated]

I am going to make up a couple of dummy boards ready for transfering a nuc to a full size brood box.

Do I make it with bee space all around (6mm) of to make it a tight fit, which the bees may seal with proplise.

Thanks

A dummy board is the same dimensions as a frame - except for thickness (about half the thickness).
So it should have about 8mm beespace each side.

A divider board (different thing for a different job) would fit tight to the sides, and extend down to at least the full depth of the box.
