AT&T SYSTIMAX M-Series Snap-In Unloaded Blank Module Insert, Electrical Ivory: A non-functional solid plastic filler block element engineered to snap flush into any empty M-Series frame or faceplate aperture. It is used in real life to cleanly seal off open, unused port slots in an outlet plate, preventing dust, humidity, or fingers from slipping inside the electrical wall cavity while maintaining a uniform appearance.
