USPS Approved Centralized Mailboxes

Our robust versatile™ 4C mailbox line was developed with a simple to use modular system that provides a very flexible solution for your individual project needs – taking the guesswork out of meeting the necessary USPS requirements and/or ADA Fair Housing requirements, too. Standard pre-configured options are available for simple installations, or custom-build a solution from a base unit to make your centralized mail center stand out from the rest. Available in three mounting types, this indoor/outdoor solution can effectively replace an outdated mailbox installation or be designed for any new construction project.

4C Recessed Mount Mailboxes
The versatile™ 4C mailbox suites offer 12 different heights with over 140 pre-configured individual modules. Suite heights provide greater flexibility in ensuring your mailbox installation remains compliant with necessary regulations. The Max Height Suite for instance, is designed to ensure a maximum number of USPS compliant tenant compartments are available within the allowed space; while the ADA Max Height Suite ensures a maximum number of compliant tenant compartments to completely meet both Fair Housing ADA installation requirements and Postal requirements. Multi-Unit Connector Kits (MUCK) are available to secure multiple units across a larger rough opening, eliminating the need for wall studs. It also ensures a clean look for flush side by side mounting, reducing any gap between modules.
4C Surface Mount Mailboxes
Designed for indoor or outdoor use, this heavy duty mailbox enclosure allows 4C modules to easily be mounted to any flat surface. A mounting collar is included with all 4C-SM modules and is ideal for settings with limited wall depth or material that makes it difficult to cut in a rough opening. The surface collar matches the 4C module ensuring your final installation achieves a sleek, finished look while the easy-to-assemble slotted back design of the collar also simplifies installation.
