  • Our postal use letter locker mailbox requires local postmaster approval and comes with the front door prepared for the USPS postal lock, which the post office installs-free of charge. (if they approve of it)
  • Our standard letter locker mailbox comes with a pull down type front door which doesn’?t require the postal carrier to have a key. This unit also includes a secure chute that prevents a person from reaching in and stealing your mail.
