Plastic, Round Disc Entrance Reducer

These small rotating entrance discs are designed for closing off the entrance of a bee hive with the option of multiple entrance types. The disc is 3-inches white and attaches with a nail or screw through the middle. These are commonly used in swarm traps or with nucleus hives.   The largest opening on the disc measures 15/16-inch.   The entrance has a fully open, queen excluder, closed but ventilated, and a restricted size. These entrance dials are extremely helpful when setting up swarm traps.
