The remote-controlled cable operator for balancing dampers is available completely assembled for installation on Model RCS-213 (round) and RCS-215 (rectangular/square) dampers. It has a 1-13/64-inch opening in ceilings and walls for architectural requirements. Opening and closing the damper is accomplished by use of an Allen head screwdriver, while the screw-drive assembly holds the blade in a constant position, regardless of airflow, states the company. This remote-controlled cable operator also is sold separately for use in various volume-control applications.
