The centre hole can be removed and a feeder placed over it. Alternatively, an eight way or rhombus style bee escape can be placed under the hole and used to clear supers. Heat from the hive will rise through the crown board vents, if opened. This can be used to heat a split brood box with 2 small nucleus colonies over the winter.
National Poly Crown Board, Multiple Holes
The crown board is unique. It is highly insulated and equipped with five holes which can be blocked or opened for ventilation depending on the choice of block. Solid or ventilated blocks are included.
