Clear Crown Board
6mm exterior top quality perspex framed with pine laths. Bee space on both sides for Nationals. Has a cut out slots for a plastic porter bee escape, which are included. This board provides good insulation when in its usual position above the top super and below the roof. It is also used when clearing the bees with porter escapes. When feeding bees, the feed is placed directly over one of the slots if using a rapid feeder, or both slots if using a bucket contact feeder. In the winter, the crown board is often placed directly over the brood body.
