The Flex puller worked great for installing my new Chimney Liner. I installed the DruaVent Flex in my existing Class A chimney for venting my new condensing boiler. The existing chimney was in the ideal location but not approved for condensing appliances. The Flex puller made short work of installing the new liner.
