Product Description

The Seal Tight Damper is constructed of cast-aluminum and stainless steel which means this damper won't rust or corrode. It is American made right in Atlanta Georgia. It features a comprehensive silicone seal gasket and solid silicone rubber gasket that seals virtually 99 percent of the damper frame.
