    Does this have a gasket that the fins seal against when closed? Does this have a spring or springs to keep the fins flush against the gasket? Many thanks!

    Thank you for your question on the Broan 438. The Broan 438 does have a foam seal that the damper flaps rest on. This foam goes all the way around the Broan 438. This damper is a gravity style damper. The damper flaps are held in place by a vinyl cloth material. If you have further questions please contact Technical Support directly at 800-637-1453.
