USPS Approved for Replacement Use
Salsbury Industries 4B+ vertical (3500 series) and 4B+ horizontal (3600 series) mailboxes have been U.S.P.S approved to the required security upgrades of USPS-STD-4B+. These mailboxes are approved for replacement and /or retrofit installations effective October 2006. For new construction or major remodels, 4C horizontal mailboxes (3700 series) are required.
The demand for improved mailbox security prompted the United States Postal Service to develop this standard. The standard requires manufacturers to strengthen and improve the master door (arrow lock compartment) on vertical style apartment house mail receptacles (3500 series) and horizontal style apartment house mail receptacles (3600 series).
