Abstract
A damper blade is constructed with a laterally extending, rounded rib and with integral journals on opposite ends of the rib that form bearing surfaces when the blade is journaled in openings in the frame of a damper assembly. The construction provides for convenient manufacturing from a blank without the addition of hardware for mounting the blade in a damper assembly.
