This is a beautiful mailbox!!! Installation was ridiculous, however.... the mounting screws were long and impossible to correctly install ... the bottom holes need to be applied on the INSIDE of the mailbox which only allows a few inches... impossible to get a screwdriver, or even your hand fingers in there to tighten the screws. I think there should be a slotted mount ( acres are placed on wall to anchor and the ‘key hole’ slotted mount could be easily managed ... leaving the bad secure... gave up with only 3 screws holding the box in place ... 
but still is a beautiful mailbox... worth the effort... to me
