Cluster Box Unit (CBU)

Product Overview

 Centralized mail delivery equipment can be in the form of any "clustered" style of mailboxes, but the most popular is the free-standing, pedestal-mounted cluster mailbox or Cluster Box Unit (CBU). These USPS Approved units are most often used in outdoor new construction installations, but are also popular in commercial and retail settings. These pedestal-mounted units are widely used for safe, secure access to mail and package delivery 24 hours a day by multiple residents in one central location. Dress up your basic CBU with decorative accessories in two distinct styles to fit your neighborhood.
