Raccoons trying to get on my Boss Buck gravity feeder 

I put a piece of 6 inch SDR pipe over the post and then go to Lowe’s and pick up a black plastic water heater pan. Cut an X in the center of that water heater pan just enough to fit over the post and let it rest on top of the 6 inch pipe. It’s like an umbrella. They can’t get past it. One thing you must make sure that your feeder tubes to the bottom of them are 42 inches. The raccoons cannot jump that high. Hope that helps.
