Selecting the appropriate mailbox for your facility is a decision that demands careful consideration. Among the myriad of options available, one of the most significant distinctions lies between 4C front loading mailboxes and 4B+ horizontal mailboxes. In this comprehensive guide, you'll be presented with all the necessary information to make an informed choice on selecting the appropriate mailbox that best suits your business, apartment complex, or any other development you own or manage. Florence Corporation and Salsbury Industries are both trusted commercial mailboox manufacturers of 4C mailboxes and 4B+ horizontal mailboxes. Each offers a wide range of USPS-approved mailboxes, ensuring a durable and attractive addition to your facility.

Understanding 4C Horizontal Mailboxes

Let's delve into the world of USPS STD-4C mailboxes, which are centralized, wall-mounted mailboxes required for new constructions and major renovations. Florence and Salsbury produce a large selection of USPS-approved 4C  mailboxes, designed with the utmost care and attention to detail. These mailboxes are constructed using heavy-duty aluminum and stainless steel hardware, guaranteeing longevity and robustness. Available in configurations of 1 door wide (single column) and 2 doors wide (double column), you can choose from an array of colors, including antique and dark bronze, black, gold speck, grey, sandstone, silver and white, to complement your facility's aesthetics.

Security is paramount, and to that end all 4C mailboxes are are constructured with built-in heavy-duty cam locks and anti-fish plates that prevent tampering and unauthorized access. Furthermore, the USPS mandates that every 4C mailbox configuration must have 1 parcel locker for every 5 mailbox doors, facilitating the smooth delivery of larger packages. Your building tenants will appreciate the convenience and reliability of these mailboxes.

Additionally, 4C mailboxes come with a 5-year warranty, assuring you of their quality and durability. These mailboxes are well-suited for multifamily housing units, apartment complexes, commercial buildings, government and military bases, schools, colleges, and other residential and commercial developments.

Varieties of 4C Front Load Mailboxes

To cater to diverse requirements, 4C horizontal mailboxes are available as:

• Recessed Mounted Mailboxes: Available in a variety of heights – from 16 door to 6 door high units – these mailboxes offer both front loading compartments. The outgoing mail collection compartment features a weather-protected flap and mail slot for added convenience. 

• Surface Mounted Mailboxes: Designed for ease of access, 4C surface-mounted mailboxes feature one or two easy-opening master door panels, allowing mail carriers seamless access. They include a USPS-approved 4C mailbox with a matching surface-mounted enclosure.

• Free-standing Mailboxes: Flexibility is the hallmark of 4C free-standing mailboxes. Simple to assemble, these mailboxes come with a USPS-approved 4C mailbox and a matching free-standing enclosure. Ideal for locations where wall-mounted applications are not preferred or available.

Exploring 4B+ Horizontal Mailboxes

In contrast to 4C horizontal mailboxes, 4B+ horizontal mailboxes are primarily used for direct one-to-one replacements. The USPS permits their use for replacements as long as no changes are made to the rough opening where the existing wall-mounted mailboxes are currently installed. It is always prudent to verify with your local post office before purchasing any mailboxes to ensure compliance with regulations.

4B+ horizontal style commercial mailboxes are crafted with precision, making them suitable for various settings such as office buildings, apartments, condominiums, and residential developments. Constructed from aluminum and stainless steel hardware, these mailboxes boast a powder-coated finish available in aluminum, bronze, or sandstone, adding a touch of elegance to any environment. The 3600 series 4B+ horizontal mailboxes can be recessed mounted and come as front loading units or rear loading units, providing flexibility to meet your specific requirements.

Each door of the 4B+ horizontal mailboxes includes a five-pin cylinder cam lock with two keys, ensuring security and privacy for the mailbox users. Moreover, the front loading door panel swings on a continuous hinge, allowing mail carriers easy access for convenient delivery. For a personal touch, optional engraved placards and custom engraving are available for doors.

 

Choosing the Right Mailbox for Your Facility 

To make an informed decision between 4C mailboxes and 4B+ horizontal mailboxes, consider the nature of your facility and the specific requirements:

• New Constructions and Major Renovations: If your facility is undergoing new construction or significant renovations that involve modifying the wall where existing mailboxes are installed, USPS STD-4C mailboxes are the way to go. These centralized, wall-mounted mailboxes are the USPS standard for such projects.

• One-to-One Replacements: For scenarios where the mailboxes' rough openings remain unchanged, 4B+ horizontal mailboxes serve as direct replacements, subject to USPS approval. These mailboxes are suitable when you intend to maintain the same amount of space occupied by the existing mailboxes.

• Facility Type: Consider the nature of your facility while choosing between 4C mailboxes and 4B+ horizontal mailboxes. 4B+ horizontal mailboxes are particularly well-suited for apartment complexes and other residential developments. On the other hand, 4C horizontal mailboxes prove ideal for commercial buildings and multifamily housing units.
