Installation of a gear driven cable operated damper allows the balancing
contractor a convenient way to adjust air volume from a more accessible location without having to access
the ceiling. The gear driven cable operated damper is mounted upstream of the air device with the control
cable inside of the airstream. The actuator at the end of the adjustment cable is accessible from the diffuser
grille. The gear actuator features a hex head so adjustments can be made easily and then locked in place
with a standard 1/4’’ screwdriver or nut driver.
