Materials used to construct the item are Stained Glass, Mirror, Copper, and silver solder.
For wood doors use wood screws that will fit in the support loops, metal screws for metal doors, and for Renters not wishing to damage property can use small patches of velcro with adhesive backing. Do not over tighten screws or the loops could be damaged. Each escutcheon is designed to fit over standard conventional door knobs. If you have a lever handle place the escutcheon through the handle at an angle and it will fit around it.
Door knobs are for display only. Make sure you measure the distance of your doorknob to the lock area so it does not reach it or you will damage the item when you open or close the door. Compare the room that you have to the item size description. Some of these items can be reversed if needed. All solder darkens with age. To prolong the metal sheen use a spray wax at least three times per year. Any questions at all please ask before you order something you are not sure about.
