USPS-Approved Cluster Mailboxes from Dwixt

Streamline and secure mail delivery for your community with our USPS-approved cluster mailboxes.

What Are Cluster Box Units (CBUs)?

Cluster box units (CBUs) are pedestal-style mailbox systems designed for centralized mail distribution. They typically include 8, 12, 13, or 16 locking compartments—each assigned to a resident or tenant—and at least one larger parcel locker for bigger packages. A key is issued to each resident for their individual compartment, while the USPS handles the master lock for simplified installation and maintenance.

Why Choose USPS-Approved Mailboxes?

• Compliance & Convenience: Ensure reliable, uninterrupted mail service.
• Enhanced Security: Protect sensitive mail with secure locks and outgoing mail slots.
• Package Handling: Larger parcel lockers allow residents to pick up packages safely and easily.

Selecting the Right Cluster Mailbox

When choosing a CBU for your property, keep these factors in mind:

• Number of Units: Select from 8, 12, 13, or 16 compartments to accommodate all residents.
• Security Features: Opt for high-security CBUs with theft-proof fasteners and reinforced doors.
• Style & Aesthetics: Choose a design that complements your property’s look and feel.
• Size Options: Standard (3” x 12” x 15”), Large (4.75” x 12” x 15”), and Extra-Large (6.5” x 12” x 15”) compartments.
