4″ Cape Backdraft Damper
The Cape Backdraft Damper will stop even the slightest amount of air from entering your home through bath fan ducts and dryer ducts. The specially designed sleeve closes down when the fan or dryer is off preventing any outside air from coming in. With the fan or dryer on, the Cape Backdraft Damper opens up with almost no resistance allowing your appliance to perform at its maximum efficiency. The specially formulated fabric sleeve allows maximum air flow only in the desired direction. The innovative design is easy to install in existing ducts. Unlike traditional backdraft dampers, the Cape Backdraft Damper has no mechanical parts to worry about sticking open or breaking. This product will make your home more energy-efficient and comfortable. Proudly made in the USA.
The Tamarack Cape Backdraft Damper was featured on the “Today” show.
