Wall plates are flat, decorative covers that are installed over electrical outlets, switches, or junction boxes in a building. They serve to protect the wiring and provide a finished look to the wall. Wall plates come in various materials, colors, and designs, allowing homeowners to choose options that match their interior decor. Typically made from plastic, metal, or wood, wall plates are easy to install and can be replaced without professional help. They are available in standard sizes to fit most outlets and switches, including those for light switches and power outlets. Proper installation ensures safety and enhances the overall appearance of a room.
