Continental Fan Manufacturing BDD150 Reviews

Rated 5 out of 5 by from Damper Super easy install and works excellent. Top quality product, goes inside the duct so there is no cutting and uses less space. Fits perfect glad I used this.

Rated 5 out of 5 by from Easy to install Solid construction. Except for the crawl under the house, installation in an existing 6" exhaust run was easy. Fits inside the duct (snuggly thanks to the gasket) so no cutting is required. Perfect solution for a downdraft range vent, when the damper on the outside duct cover wasn't keeping out the cold air.
