The Cardboard Nuc Box has become very popular with Beekeepers for several reasons. If you sell Nuc's you don't have to worry about unreturned equipment. They are also excellent in the bee yard for making splits, queen banks, swarm traps, or pollination hives. They are very simple in design and lightweight with the weight of the frames transferred to the bottom of the box. A plastic cap plug is included for easy transport of your bees. Approximate dimensions 19.5"x11"x9".
