Our Glass Mirror Switch Cover Plates have highly polished 5/16" (8 mm) wide beveled edges, and are cut from quality 3/16" (5 mm) plate glass. There are a total of 45 different styles to choose from in single, double, triple, quad, five and six-gang, including a variety of blank plates. They are ideal if you use lots of a particular style of plate, or need to have a ready supply of spares for your counter-top display. All come in three standard colors: Clear, bronze, and gray. Other colors are available on special order, and we can even cut plates out of the same colored mirror being used on your job. Custom cover plate configurations are also possible; just send us your drawing. All plates are individually blister carded in an attractive retail package. Mounting screws and plastic spacers included with each pack. Bulk Packs are a good way to cut your costs and, at the same time, maintain your cover plate inventory. Important Notes: 2-3/8" (60 mm) center-to-center screw hole spacing.
