The bottom board serves as the foundation and entrance to the hive. Our two-sided, reversible beehive bottom board has a 1/8" entrance on one side and a 3/4" entrance on the other. Why the two different-sized sides? The 3/4" size is standard height to use with a wooden entrance reducer (and the extra 1/2" below allows for air flow). You can turn it over to use the 1/2" opening as a smaller opening. This is just if you want a smaller opening - there's no other great benefit.
Comes fully assembled: screwed not nailed.
Includes wooden entrance reducer for winter use or new hives.
