JC, my feeder is similar to this one. It holds four socks. It is a pole - and therefor squirrel proof. I had it set in concrete, so it is quite stable. You can find feeder poles at bird stores, or order one online. I sure recommend it!
That was a pretty large shepherd’s hook I bought at Lowe’s but those little boogers climbed right up! Chewed off the perches the little goldfinches used.
Those pan-like things on your pole, what do you put there?
