3 BetterBee 10 frame vertical slatted racks used one season for Langstroth hives.
$20 cash for each ($50 if you buy all 3 together). No barter or trades. Buyer must pick up in Reading.
Use this vertical slatted rack between your bottom board and brood box to give the bees some extra space and ventilation in the hotter months!
In the winter, a slatted rack keeps the brood chamber warmer so the queen can lay right to the bottom of the frame. In the spring and summer, when hive populations are at their largest, it provides a cluster space in the hive which can reduce swarming. Slats run perpendicular to the entrance.
