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 Available in three mounting types, this indoor/outdoor solution can effectively replace an outdated mailbox installation or be designed for any new construction project.
