Poly National 14x12 Jumbo Brood Box

Part of out Poly National Range.   Totally compatible with both our wooden National hives and Poly National hive components, the only combination is that a wooden roof will not fit over a poly brood box or super.    Use your existing hive parts and take advantage of the polystyrene benefits:

its made from a very high density material, 100g/litre - upto 3 times stronger than what is used for packaging.
Its lightweight and durable.
Its insulation properties also makes it ideal as less bees are required to maintain the heat required for effective brood rearing, helps improve overwintering and early Spring buildup.

A 14x12 Jumbo Brood Box for National hives.      Can you used on our poly National hive or our wooden National hives.
