The 10 framemedium super(commercial grade). The medium super is where the colony will deposit the honey into the hive. Our wood is Eastern White Pine from the New England area. Our wood is then shipped to Toccoa, GA where it is then manufactured. Eastern White Pine wood allows for extended use time in the apiary versus other woods. The D-handle allows you to have a deep grip when having to move the brood box by hand or with a hive carrier. The end joints allow better stability and reduce cupping over time. All nail holes are pre-drilled to reduce the chances of splintering with 6D nails. Please note that commercial grade wood ware has knots and is not perfect but very much usable for the average beekeeper.You will need to paint the exterior with two coats of paint to properly seal the wood from the elements.We offer this product unassembled.
