perches are about 1-2" diameter and all perches are about 5" 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. I use this for a sleep perch, I even use them for the littles. Its like a platform for them.
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
