All the ceramic switch-plate and outlet covers are original designs and available in multiple configurations. All switch-plates will fit on standard North American switches and receptacles. You will find these switch and outlet covers are thicker and slightly larger than the typical plastic receptacle and switch covers. With each switch cover, you will receive extra-length nylon screws. The nylon screws are less likely to crack the ceramic. Combination switch-receptacle plates are all reversible to satisfy different configurations. For configurations not in stock, please allow 3-4 weeks.
