Top-Bar Hive Nucleus Box

21   |  

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!

Always Good

I am a repeat customer and have consistently received excellent customer service and great products. I stopped in last time I was in PDX and sampled and purchased some mead. Keep up the awesomeness! . . . Mike Blakey, Anchorage, Alaska

My Nucleus Box is great.

My Nucleus Box is great. However, in a more recent order, I received a Bee Brush which broke the first time I tapped it on the side of the beehive. Please advise! Thank you. Anne

Sugar Pine is our value wood option. Beautiful, strong, takes paint or sealant well, and is more stable and lighter than more common ponderosa pine.

Western Red Cedar is our premium wood option. It is rot resistant, dimensionally stable, insulates well, and doesn't require painting or sealing.

All of our wood is sustainably harvested and FSC (Forest Stewardship Council) certified.
