Louvered Vents
Louvered dampers are the slatted devices just behind a grille which can be adjusted to control the flow of air. Louvers are installed separately from the grille using screws. Allow enough clearance behind the grille so the louvers can operate freely when installed.
We sell Louvered dampers to fit all of our Grilles.
4"x10" $16
4"x12" $18
Louvers can be adjusted by using a flat head screw driver.
Purchase the adjustable damper and grille in the same size.
