Dampers

Opposed Blade Dampers are used to control the air flow on supply grilles. This type of damper fits inside the duct.
These dampers are open and closed with a screwdriver inserted through the ornamental grille, so that no adjustment lever is seen. The Dampers fit all our styles of decorative grilles. Use them on supply grilles only, to adjust the amount of air flow. Use only with decorative grilles where periodic adjustment of air flow is necessary. Dampers are not necessary on all grilles. Most new houses have a free flow design making dampers like these unnecessary. More sizes are available as special orders. Prices may vary. Installation Information
