A door escutcheon is a metal or plastic border that is attached to the center of a door. The escutcheon is used to strengthen and protect the door's lock against the door being forcibly opened or the lock being forced. The escutcheon can also serve as a decorative element on the door. There are various types of door escutcheons available, with different shapes and styles depending on the desired look and the level of security needed. Some door escutcheons also have additional security features, such as a cylinder or a security plate, to prevent the lock from being forced.
