8-Frame Slatted Rack
In the spring and summer, when hive populations are at their largest, slatted racks provides a cluster space in the hive. The additional space can reduce swarming and bearding at hive entrance. In the winter, a slatted rack keeps the brood chamber warmer so the queen can lay right to the bottom of the frame. Place slatted racks between your bottom board and brood box.
