I have come into possession of 7 or 8 of these things. They are the same size as an inner cover but instead of the solid plywood in the centre they have 2 layers of #8 hardware cloth with about a 3/8 to 1/2" gap between them. On one side there is a swivel type door arrangement to allow bees to come and go. I am not sure of the original purpose or name for it. I have just used one to combine a small 3 frame nuc on top of a hive that had an old drone laying queen (pinched yesterday). The nuc was placed in a deep super on top of this screen set up and the door was placed facing up to allow those bees to enter/exit. The hive below can come and go as it always has. I hope this will allow the pheremone from the queen in the upper box to take over and then after several days I can do an easy combine.
Make sense? Anything wrong with this? What is the actual name for it and the original purpose?
Thanks
