This seemed to work adequately. I wrapped each connection with duct tape, as others have suggested, to avoid the risk of getting the brush stuck in the chimney if they became disconnected.One of the sections snapped on the first use though so I have some doubts about the longevity of the product. Fortunately, I bought much more length than I needed so am okay for now.
