So I needed a 4 foot tube for my bees to exit on the other side of a hedge. This lets the public view the hive without any chance of bee/human interaction at the hive entrance. (The other side of the hedge is 20 feet from any human path.)

Let me know what you think!
I’m a little concerned this won’t provide a large enough entrance for the bees during a strong honey flow.
