"Our standard 10-Frame hive body is divided into two 4-frame Nucs. Add two 4-frame Nuc boxes and your Nucs will have room to expand. The screened bottom board is also divided and has alternate entrances for each chamber to prevent robbing and drifting between colonies. It is great for overwintering Nucs, as a tool used for raising queens, creating splits or boosting weaker colonies with brood. Includes Bottom board, Divided 10-frame box, and two 4-frame Nucs to fit the 10 frame box. Fully assembled. Finish the resource hive with a standard 10 frame telescoping top (not included)."
