Product Details

Fire dampers offer protection in the case of a fire by preventing the flames from spreading through your ventilation and air ducts. Damper must be kept clean and protected from dirt, dust and other foreign materials prior to and after installation. Caulking is not necessary, nor is it allowed, between the damper sleeve and the wall or floor opening.
