There is a lip running around the circumference of the crown board which fits into the recess of the roof’s underside securing it for transport and preventing it from sliding. In the centre of the board is a moulded docking station for one of our 2.4L Ashforth feeders and a hole at one end of the dock, allowing the bees to come up from the brood box and into the feeder.There is also an additional circular hole in the centre of the dock for fondant. Comes complete with polystyrene plug and vents for both holes.

** Feeder not included **

This crown board only works with the 12 Frame Premium National Poly Hive.
