More Info About Commercial Building Mailboxes
Salsbury Industries offers a complete line of quality mailboxes for commercial buildings. These mailboxes are available for new installations, and retrofit and replacement applications.

Indoor Mailboxes for Commercial Buildings
4C horizontal mailboxes are the most popular indoor mailbox used in commercial buildings. Unlike pedestal mounted mailboxes such as the cluster mailbox unit, 3700 series 4C horizontal mailboxes are typically recessed into the wall. Available in aluminum, bronze, sandstone and black, 4C horizontal mailboxes are made of heavy-duty aluminum with stainless steel hardware and are ideal for office buildings, hotels, apartment complexes, government offices, universities, medical centers and other commercial developments. Salsbury Industries offers 4C horizontal mailboxes in recessed mounted, surface mounted and free-standing models.

Outdoor Mailboxes for Commercial Buildings
The 3300 series cluster box unit (CBU) is a free-standing mailbox option for commercial buildings. Cluster mailboxes are USPS approved and are ideal for office complexes, industrial buildings, medical centers, hotels, retail stores, multifamily housing locations, warehouses and other commercial applications.
These units are extremely secure with heavy-duty cam locks and anti-fish plates to prevent mail tampering. CBUs include a pedestal and are available in 4, 8, 12, 13, and 16 mailbox door configurations (plus parcel lockers for package delivery). Designed with elegance in mind, Salsbury Industries also offers regency decorative cluster mailboxes that come with a decorative top and decorative pedestal cover. Cluster box units are available in sandstone, bronze, white, green, black and gray.

Other Mailboxes for Commercial Buildings
Designed for replacement and retrofit installations, Salsbury 4B+ horizontal style commercial mailboxes are another commonly used wall mounted commercial building mailbox. Available as a recessed mounted unit, the Salsbury 4B+ horizontal style mailbox is made entirely of aluminum and available in 3 colors – aluminum, bronze and sandstone. 4B+ mailboxes are also available as vertical units that come in 3-door, 4-door, 5-door, 6-door, and 7-door configurations. The 4B+ vertical mailboxes can be purchased as recessed mounted or surface mounted units and are also available in aluminum, bronze and sandstone colors.

USPS Mailbox Requirements for Commercial Buildings
USPS commercial mailbox requirements dictate that all new construction and major renovations must meet current USPS specifications. Commercial mailboxes for U.S.P.S. delivery include cluster box units (CBUs) and 4C horizontal mailboxes. 4B+ horizontal mailboxes and 4B+ vertical mailboxes can be used for retrofit applications only. USPS approved mailbox products are commonly used in apartment complexes, commercial buildings, residential developments, condominiums and several other applications.
