Roof sits snugly on top of the crown board, giving the entire hive a slim-lined look. It is embossed with a recessed plastic hive strap guard which runs across the middle of the roof for extra protection when strapping up hives for transport or winter. On the underside of the roof there is also a recess 20mm in from it’s circumference to provide a snug fitting onto the crown board.
This roof only works with the 12 Frame Premium National Poly Hive.
