With numerous pre-configured 4C modules available, our 4C mailboxes are also an excellent option for private delivery applications. This 4C module is not approved for Postal delivery as it cannot be mounted to adhere to all USPS installation regulations – but is an ideal choice for Private delivery applications. In settings with limited wall depth, this mailbox module provides greater flexibility in mailbox placement and installation.
Designed for indoor or outdoor use, this heavy-duty STD-4C mailbox enclosure allows standard modules to quickly and easily be mounted to any flat surface. The easy-to-assemble collar has an industry exclusive slotted back design for ease in installation and reduction of overall unit weight.
