4B Horizontal Mailboxes

The MailboxWorks carries both rear loading and front-loading commercial horizontal mailboxes. Both can be utilized for USPS mail delivery or private mail delivery services. For USPS mail delivery, your local post office will install a USPS master lock and a postal employee will deliver the mail. Although they are USPS approved, 4B+ horizontal mailboxes are only for mailbox replacement use.

Centralized mail delivery systems provide efficient mail delivery and collection services to multiple residential and commercial customers from a centrally located mailbox installation. Today, the USPS requires that all new construction for residential, commercial, and institutional properties (both single and multifamily) must have a centralized mail delivery system installed. You can find more detailed information in this Florence Corporation publication, Designing a Compliant Centralized Mailbox Installation.

Rear & Front Loading

Residential and commercial horizontal mailboxes enjoy widespread use across North America. There are two primary types of 4B horizontal mailboxes that can be purchased:

  • Front Loading Mailboxes
  • Rear Loading Mailboxes

If you are unsure whether a front or a rear loading commercial mailbox is the better option for your application please contact MailboxWorks. You can reach us Toll-Free at 1-866-717-4943.

Commercial & Apartment Mailboxes

Serviced by USPS, common applications where 4B replacement mailboxes can be found include:

  • Residential & Multi-Family Buildings

  • Government & Military Facilities
  • Schools, Universities, Colleges & Dorms
  • Financial & High-Security Institutions
  • Offices & Medical Complexes

Indoor & Outdoor Mailboxes

Both indoor and outdoor 4B mailboxes must provide the highest level of security for centralized mail delivery systems. Thanks to concealed hinges, tamper-resistant master doors, and heavy gauge aluminum construction approved by USPS, Florence horizontal mailboxes do exactly that.

Indoor 4B horizontal mailboxes are designed for indoor recessed installation. When ordering, please indicate whether you want a front loading or rear-loading mailbox design.
