Rock-Flex Chimney Liner Coupler Options - Informational Video

You may need to connect two sections of chimney liner together if you didn't initially order enough flexible liner, if you are choosing to extend the masonry chimney, or the length of liner you need is simply too long to handle in one section. For whichever reason, it is simple to attach two sections of Rock-Flex chimney liner together with our coupler options. Please call us with any additional questions you may have at 866-708-2446
