Most Ultimate Support stands feature field-replaceable parts. In the unlikely event that a part on an Ultimate Support product breaks, you'll be able to simply replace the part affordably rather than replacing the entire stand. If you don't find the part you're looking for here on our website, please don't hesitate to contact our Ultimate Support's Service and Support department who will do everything they can to help you.
