The ENERLITES 7731MA metal wall plate fits over any standard decorator outlet or switch. At the mid-size of 4.88" x 3.11", this wall plate covers a little more wall space than a standard size one, which is perfect for covering up damage that may have happened during installation. Made from solid stainless steel, this mid-size decorator switch wall plate is non-combustible and offers both heat and corrosion resistance. The wall plate is also made with a silver ion additive to provide antimicrobial properties. Silver ions work on a cellular level, preventing the growth and survival of unwanted microorganisms such as mold, mildew, fungus, and bacteria.
