“This attaches easily to the base of the flythough bird feeder, but is narrower than advertised. The one inch pole I purchased to slot it into was too wide. I ended up using a a half inch pole, and I wrapped the top with a few layers of duct tape to get a snugger fit. If you plan to buy a pole locally, wait until this arrives and take it to the hardware store with you to make sure you get a good fit.”
