- Model OBD is used on registers and grilles. OBDDM is used for duct mounting. Opposed-blade dampers have vertical blades that move in opposite directions to control air volume over the entire face of a register or grille.
- Interwoven tension spring on blade pivot points permits positive setting from full-open to full-closed. Blades are screwdriver operated. Extremely shallow depth allows damper use in shallow stackheads.
- Extruded aluminum or steel. Mill finish standard.
- OBD14 available for use on 1400 series only.
