To install the disk, you must open a 30-40mm hole on the beehive side. The disk is installed on the hive by passing a screw through the disc center.
It features 4 positions/“settings”: (i) completely closed, (ii) completely open, (iii) bee queen excluder and (iv) protection from hornets.
TIP: Can be used for multiplication and merging of colonies. Making a 4 cm hole and installing two discs on a wooden sheet with same dimensions as the beehive, allows you, by changing disc “settings” to use the structure for queen separation (exclusion) and merging of colonies: first leave the discs at “completely closed” position with ventilation for 1-2 days, allowing the transfer of smell between the two colonies; then turn both discs to “queen excluder” position, thus allowing communication of the bees, while the queens keep giving birth without being able to contact/harm each other (since the discs/excluders are placed in between the two different floors created by the installation of the wood/disc structure).
