DuraVent DuraFlex Aluminum 3 Inch Diameter Flex Liner Kit - 25 Foot Length

The DuraVent DuraFlex Aluminum 3 Inch Diameter Flex Liner Kit is a smart way to get your chimney working great again. This tough aluminum liner fits right into your masonry chimney, giving it a smooth, new inside surface. It's designed for a snug fit, needing only a tiny bit of space from the brickwork, which is pretty neat. You'll find everything you need in the box to get it all set up, like the liner itself, a cap for the top, a sturdy plate, and a sleeve for sealing with mortar. Using this liner really helps keep your chimney in good shape by shielding it from the gunk that can build up from burning wood. It's a solid choice for anyone looking to improve their chimney's performance and longevity.
