Choosing the right Vertical Mailbox for your commercial location or apartment complex

Our selection of commercial and apartment style vertical mailboxes starts with the 3 tenant door unit and goes all the way up to the 7 tenant door option. Important note: while these units are approved by the USPS for the replacement of pre-existing vertical mailbox installations, we strongly recommend you contact your local postmaster for approval before purchasing and installing vertical mailboxes at your location. If you are purchasing commercial mailboxes for a new construction development or project, you will need to go with the USPS approved cluster box. All vertical style commercial mailboxes on are manufactured by either Florence Mailboxes or Salsbury Industries.
