Abstract
In a sealing mechanism for a damper plate for a duct, seal members are made in the form of multi-convoluted sheet metal bellows, which engage each side of the damper plate around the periphery of the duct. When the duct is moved from an open position to a closed position, it slides between the seal elements forcing them apart. When the plate is slid from a closed position to an open position, the spring bias in the bellows members will cause them to expand to engage each other.
