This piece of equipment will make your requeening "FOOLPROOF". When you divide a colony put a Double Screen Board on top of the old colony and place the new split on top. The old colony below keeps the environment perfect for the split above, thereby reducing stress. the old foraging bees left upstairs will pageant back to the old colony leaving only young bees upstairs, they will accept the new queen more readily. The screen has a variety of entrances available for use with either or both colonies. The Double Screen can be replaced with a queen excluder and you can run a double queen colony. You can also use the Double Screen for ventilation by screwing it to the top of a colony you are moving.
