Our Flower Pot Holders come with a 6" detachable ring. They are made out of mild steel and will eventually weather over time. There are basically 2 widths and 2 heights available. They can vary slightly as each is individually handmade. The single width at approx 6"-7" and the wider width at approx 10"-11". Heights can vary from 16" - 24" tall. We may not have pictures of all styles, so please email if you are interested in more options than what you see on the website.
