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.

How can my business accommodate packages?

If your business has USPS STD-4C horizontal mailboxes, one parcel locker is required for every five customer compartments. A parcel locker is a lockable unit where mail carriers can leave larger items that won’t fit in a standard mailbox.

Do I order 4C or 4B+ mailboxes for my commercial building?

USPS STD-4C horizontal mailboxes are required for new construction and major renovations, while you can only use 4B horizontal and 4B vertical mailboxes for direct one-to-one replacements. If you don’t have to make any changes to the rough opening where the existing wall-mounted mailboxes are currently installed, 4B horizontal or 4B vertical mailboxes can be used (though you should always check with your local Post Office to be sure). Otherwise, 4C horizontal mailboxes must be used. Click here to view information in selecting the right mailbox for your application.
