Buy screwless brown plastic wall plates covers made in USA to richly complement to warm woods and natural paint colors. Brown hidden-screw switch plates are only manufactured with rocker openings for 1-6 gangs. See brown metal light switch covers for more than 100 sizes.
To install this Lutron wall plate, screw the sub-plate into the device. Cover then snaps over.
Screwless covers all come with rocker openings.
If you need a blank cover without screws, simply add blank rocker switch inserts to convert these plates for an empty electrical box.
