Whether you are installing a cluster box unit or a bank of 4C mailboxes, we can help you access your mailbox needs and navigate USPS and Utah requirements.

Centralized mail delivery is the most efficient method for the U.S. Postal Service. Besides keeping the cost of mail delivery down, it also:

• Keeps mail secure from theft.
• Speeds up mail delivery by reducing the number of stops.
• Makes it so that individuals don't have to be present to receive packages.
• Does a better job at protecting packages and letters from the elements.
• Enhances the appearance of the neighborhood by eliminating individual curbside mailboxes.
• Is cheaper than installing individual mailboxes.

But centralized mail delivery requires some additional planning. There are a number of USPS regulations that dictate where multiple mailboxes can be placed, how they are installed, and how they should be constructed. In fact, mailboxes must undergo testing and meet or exceed all USPS specifications (4C mailbox standards) to be approved. Many of the standards were created so that mailboxes would stand up well to normal use and vandalism. They also take into account mail delivery efficiency and the size of mail that we normally receive.

Centralized mail delivery equipment or cluster mailboxes can come in a variety of styles and are used for a variety of purposes—including commercial mailboxes, business mailboxes, and apartment mailboxes.

What kind you pick depends on where you will be installing them and how they will be used.

Cluster Box Units (CBU)

This type of mailbox is typically used for apartment complexes or subdivisions. It is a unit with multiple locked mail boxes stacked together. It is usually freestanding and mounted on a pedestal.

Wall Mounted Mailboxes

Sometimes also called STD-4C mailboxes, this type of lockable mailbox is usually mounted in a wall or an outdoor shelter. Cannon Sales can help you decide what mailbox would work best for you and make sure you are meeting all required USPS specifications.
