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 or outside of the airstream. The actuator at the end of the adjustment cable is accessible from the diffuser grille (internal) or is routed to an appropriate area such as a wall mount (external). The gear actuator features a hex head so adjustments can be made easily and then locked in place with a 1/4″ standard nut driver or medium standard flat screw driver.
