Legrand® TradeMaster® thermoplastic wall plates are molded of rugged, practically indestructible, self-extinguishing nylon. They are so tough that they will not crack if excessive torque is applied to the installation screws. This feature makes them the preferred wall plate for hospital, industrial, institutional, and other high abuse applications as well as residential applications. They are also 3/16 inches higher and wider than the typical plastic wall plate - not enough to be apparent to the eye, but the extra size cuts costs by reducing drywall rework. Another time-saving feature includes preinstalled mounting screws on single-gang toggle, duplex, and decorator openings. Additionally, all of our wall plates and screws are color-matched to Legrand® devices so you can be assured of a prefect match every time.
