The plastic entrance disk is used to close the entrance when transporting nucs. The 4 quarters of the entrance disk are designed to:
- Allow all bees to enter or leave the hive
- Allow only worker bees to enter
- Allow both workers and drones to enter
- Close of the entrance of the hive to all bees.
The disk can be rotated to so that the correct quarter covers the nuc entrance. The disk is made of strong, durable plastic.
