The present invention provides an air duct registrer for adding forced air (heat, air conditioning), exhausting air or simply to balance air quality. The air duct register has a manifold and is designed with a removable manifold collar connectible to the flexible or rigid duct. The manifold has thumb cam fasteners to provide ease of installation from below the finished ceiling. With the duct in place above the ceiling elevation, the appropriate opening can be cut and all connections can be made below ceiling elevations via the manifold collar opening. The duct is routed through the manifold opening and connected onto the manifold collar retainer barbs. The manifold collar plate can then be snapped securely into the manifold. The grille then slides into the manifold and is pushed tight to the finished ceiling.
