Requeening frame

[Carl F]

Has anyone ever used a requeening frame like this one from Brushy Mtn.?

It looks like it would be really easy to use and give the queen some space and exposure to a lot of her new colony compared to leaving her in the shipping cage or even using a push-in cage.

If anyone has one, is the back side screened or does it have a solid surface? In the picture it looks solid but I am not sure why it would need to be. Right now mine is screened on both sides but easy to change if there is a reason. Only reason I can see to have one side solid is so the queen can back away from the screen if the colony is aggressive toward her at first and not have them coming at her from all sides...

Yes Robo made me one and it worked for a laying worker hive that I had.
