Our two-sided, reversible beehive bottom board has a 1/2" 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.
Made with rabbeted cross pieces to help keep out moisture. Comes fully assembled (screwed not nailed).
This beehive bottom board includes wooden entrance reducer for use with new hives.
