  • Mud used in electrical distribution boxes

    Mud used in electrical distribution boxes

    A mud ring, also known as a plaster ring or mud plate, is a crucial component in electrical installations. Electrical boxes are secured to structural framing, but the addition of drywall or plaster creates a gap between the box opening and the finished wall plane. This frame attaches directly to the front of a standard electrical box, acting as an extension collar.
