4B+ Vertical Mailboxes

AF Florence 4B+ mail vertical mail units are designed for use in multi-family apartment buildings, dormitories, office highrises, etc.

As of October 6, 2006, mailboxes that are 4B+ compliant will only be considered USPS Approved if they are replacing existing mailboxes. USPS regulations require the use of USPS STD-4C compliant mailbox systems on all NEW CONSTRUCTION and MAJOR RENOVATIONS. LOCAL USPS APPROVAL FOR USE OF 4B+ MAIL UNITS IS STRONGLY SUGGESTED (USPS approvals are by customer).
