10 Frame WOOD Heavy Duty Inner Cover [10-661]

Built from heavy-duty plywood, this reversible inner cover supports two-gallon feeders without sagging or warping season after season. One side lays flush for a tight seal; flip it over for the 3/8" depth side with a dado-cut notch that gives bees a second entrance and keeps airflow moving during warm weather. The center hole fits standard feeders or a bee escape for easy honey harvesting, while the cover itself acts as a breakaway barrier so propolis-sealed lids pry off cleanly without disturbing the colony. Year-round, it holds an insulating air gap above the frames that prevents winter condensation from dripping onto your bees and helps keep the hive cool in summer.
