Double Medium Nucs are a great way to house 2 small colonies in one standard size 10 frame hive body. 4 Medium Frames fit on each side of the divider and a separate entrance is located on each end of the divided bottom board. As the colonies grow add the 4 frame medium supers to give them more space. Many northern beekeepers are now using this method to overwinter nucleus colonies. Our Complete Medium Double Nuc includes an assembled divided bottom board, divided medium hive body, two 4 frame medium supers, and two assembled 4 frame inner covers. Note 10 Frame Telescoping Covers, 6 1/4" Frames, and Foundation are sold separately. Ships Unassembled
