Our Top Bar Hive nucleus box is built from 7/8" thick FSC certified Sugar Pine. It features a metal roof, 7 top bars, one follower board, 1 entrance reducing bung and 1 solid bung. 

Useful for swarm catching, splitting hives and overwintering nucleus colonies. All components pre-drilled for easy assembly. Ships free to the contiguous 48 states -- international shipping available. We keep one in our trunk all spring long just in case we spot a swarm! So handy!
