perches are about 2" diameter and all perches are about 12" long. They do NOT come with washers, they do come with a hanger bolt and wing nut. Once they are gone, they are gone. Don't wait.
My shipping prices are usually on target but, I did not weigh each perch so if shipping is over, Ill refund and if its under by more then a few bucks, I'll invoice for the difference
