The 4" Vacu-Stack chimney cap is the premier chimney cap for preventing wind related downdraft problems. Strong winds can make operating a tiny wood stove difficult. A strong wind is capable of pushing the smoke down the chimney pipe and into the home. The Vacu-Stack Chimney Caps unique design creates an updraft when wind hits the cap preventing the smoke from being pushed down the chimney. The Vacu-Stack also functions as a conventional chimney cap by protecting the chimney from rain, snow, debris, and animals. The 100% stainless steel construction will never rust and is capable of withstanding the harshest elements. The Vacu-Stack Chimney Cap is easily installed by sliding inside the chimney pipe and is held in place with a high temperature RTV silicone. Show more
