Mailbox (#4), post mount (Seven Springs, Cupertino)
8”W x 9.5”H x 20”D, aluminum mailbox with magnetic door latch. About 20 years old but in good shape. 6 mounting holes on the bottom, but only used 4. Takes a 5/16” carriage bolt, or wood screws. Replaced it with a locked box. This is too good to throw out IMHO.
