National Poly Super Box (Deep Roof Hive)

Poly National Brood Box – 11 Frame

Our Poly National Brood Box is designed to combine durability, practicality, and compatibility with traditional wooden National equipment. Manufactured from high-density expanded polystyrene (EPS), it provides excellent insulation to help maintain stable brood temperatures while remaining lightweight and easy to handle.

The brood box features improved ergonomic hand grips on two sides for easier lifting and handling, together with a clean, modern design embossed with our company logo.

A centrally positioned entrance on the front face allows for advanced brood management techniques, including swarm control and colony increase.
