The Hive Doctor Bar Entrance Reducer allows you to adjust the entrance to your liking!

Removable tabs allow you to control the size of the entrance, providing you with a fully customized entry ranging from 8mm to 50mm once all tabs are removed.

The Hive Doctor Bar Entrance Reducer slots in front of the Hive Doctor Smart Bottom Board, and can be flipped to either close or reduce the entrance, and stored in the front holding slot.
