Dummy Board (Brood Box ) for British National

Dummy  board for national hives, ( Brood Box ) used to stop bees using brace comb in boxes with less frames than their capacity. Also very handy when using Hoffman style frames, use this to 'fill in' that end gap. By removing this board first during inspections, it will make it easier to remove the other frames and limit bees getting crushed or squashed.
