• 16 Ga. Galvanized Blade
• 1/2” Round Plated CRS Rod
The SBD is our single blade balancing 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″ wide or are taller than 12″ high.
The damper blade is a formed 3V style and is controlled by the 1/2″ round control rod most
likely with the use of a quadrant. Both the control rod and the 1/2″rd x 2-1/2″ long pin on the
other end of the damper will protrude out each side of the duct.
