Materials used to construct items are stained glass, mirror, copper, and lead. Owners or Renters just remove your old switch plate with your new one, it will fit. Make sure you measure the size of this item and compare the area you wish to place the item. All solder darkens with age, and if you wish to keep the sheen use a spray wax at least three times a year. Any questions just ask me, and thank You for visiting.
