4C Horizontal Mailboxes
High Security 4C Mailbox Emerges as Commercial Mailbox Stalwart
The 4C mailbox first introduced to the commercial mailbox industry in 2006 is quickly becoming the general public’s commercial mailbox of choice. The end users seem to prefer the STD-4C horizontal mailbox due to its design, security, and versatility which in comparison to other commercial mail receptacles, the 4C mailbox clearly prevails. Originally designed and USPS sanctioned for wall installations the 4C horizontal mailbox has experienced an evolution of product options and styles as commercial mailbox suppliers seek to differentiate themselves from another. The high security 4C mailbox mimics the cluster box design and security, however offers far more flexibility in terms of customization of module configurations. Many industry insiders feel this why the STD-4C mailbox has quickly become the fast growing category of commercial mailboxes.
4C Horizontal Mailbox Styles
4C horizontal mailboxes were originally designed for new construction applications where the mailboxes were to be recessed into a wall or contractor created a mail kiosk. Commercial mailbox manufacturers seeing the popularity of the USPS-STD-4C mail receptacle aggressively pursued alternative styles of 4C horizontal mailboxes. The pursuit of alternative styles of 4C mailboxes resulted in a surface mount collar being developed allowing for recessed cabinets to be wall mounted, mail kiosks being created to provide a manufacturer provided structure for the STD-4C mailboxes, and a full line of pedestal 4C mailboxes to provide an additional choice for pedestal mailbox buyers. The 4C mailbox product extensions have been smashing success with the 4C pedestal mailboxes leading the way. If the manufacturers of commercial mailboxes can succeed in convincing the Postal Service to certify the 4C pedestal mailbox many industry insiders believe the 4C mailboxes will eventually surpass the most utilized commercial mailbox which is currently the cluster box unit.
4C Horizontal Mailbox Sizes
USA Building Supplies offers an assortment of 4C horizontal mailbox modules for clients to choose from. 4C mailbox modules throughout the commercial mailbox industry are available in;
- single column width

The width of the single and double wide USPS-STD-4C module will only vary slightly from manufacturer to manufacturer. The depth of the 4C mailbox will typically be about 17”. The other variable that does vary from commercial mailbox manufacturers is the height of the module. USA Building Supplies arranges our recessed 4C horizontal mailbox modules according to height because typically most designers and architects prefer to make module selections within the same height grouping. This selection practice also assists the installation contractor of the mailboxes. Generally speaking, most construction projects with a significant amount of residents will use the taller 4C mailbox modules to minimize the amount of wall space needed. Mid-sized and smaller 4C modules often are used in smaller construction projects. Senior housing projects are the one exception to the rule as far as relating the project size to the height of the mailbox module. This reason for this exception is the concern for resident in the upper mailbox compartments having to reach to get their mail.

The single wide 4C mailbox module has an outgoing mail collection door that doubles as the post office master entry door. Upon approaching your 4C horizontal mailbox to deliver the mail, the postal carrier will access the master door with the master key for the USPS provided arrow lock. Once the mail carrier gains access to the control door of your 4C mailbox, the letter carrier will push up on an internal lever in this compartment which will release the face panel for access to all the compartments at one time. The single wide 4C mailbox module face panel will hinge on the right side of unit and then once the mail carrier has delivered the mail he will lock the face panel back in its original position. The individual resident doors are keyed differently and the tenants can only gain access to their dedicated compartment. The 4C horizontal mailbox that is referred to as a double wide module operates similar to the single wide module. The double wide 4C mailbox module’s master access door is located in the middle of the right panel when looking at the front of the unit. Once the mail carrier gains access to your 4C mailbox, he will first open the right panel and then will gain entry to the left panel. Thus, the 4C double module will open like French doors for the USPS. The residents gain access to their mail in the same fashion as the single wide modules.
