Single Blade Damper
The SBD is our single blade damper manufactured from 16ga galvanized steel. There is no frame with this damper and it is our most economical balancing damper. This damper is not recommended for blades that exceed 48" long or are taller than 12" high. The damper is controlled by 1/2" zinc rods that are exposed on both sides of the ductwork and operated by either a hand quadrant or actuator.
