Our Air Damper Louvers are simply placed in the wall opening behind the wood grilles. The air flow is adjusted with a regular flat head screwdriver while the grille and louvers are in place. There is no need to disassemble to adjust.
This is a list of the ONLY LOUVER SIZES AVAILABLE.
These Damper Louvers are only meant to Open or Close the Airflow.
They are NOT MEANT to direct the flow of air.
