About Cluster Box Units

Our cluster mailboxes are built to USPS standards and are approved by the United States Postal Service. Our CBU's mailboxes are built in the United States and are made to the highest security standards. These Cluster Box Units have been installed in neighborhoods and for commercial mailbox purposes for decades and with recent USPS regulations it appears that they will only become more relevant. Cluster box units as they are some times referred were the primary commercial box on the market just a few years ago, however today there are new styles that are available that offer flexibility away from the 8, 12, 13 & 16 door cluster box sizes.
