Dampers

Dampers are used to control the air flow on supply grilles.  
These dampers are open and closed with a screwdriver
inserted through the ornamental grille, so that no 
adjustment lever is seen.  The screen allows 62% air
flow.

The Dampers and Screens fit all five 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.  More sizes are available as special
orders.  Prices may vary.  Installation Information
