Made of red brass with a great vintage look, this mail/letter slot does come with a back plate (inside frame plate). The backside of the slot does show ware which is shown. This area faces the door and cannot be seen otherwise. There are 4 pre-drilled holes on each corner for securing with screws.
Measurements: 10" long by 2 3/4" tall. Back plate: 10" long x 3" tall
This is just one example from thousands of vintage collectibles we have in our shop!
