Cluster Box Units (CBUs) – Secure, USPS-Approved Mail Solutions
Who We Are
At The Mailbox Pros, we specialize in the sales and installation of USPS-approved Cluster Box Units (CBUs) nationwide. For over a decade, we’ve been helping communities, property managers, and developers get the right mailbox solutions — installed the right way.
As a company built by experienced installers, not just resellers, we know that a mailbox isn’t just a product — it’s a piece of community infrastructure that needs to be secure, durable, and USPS-compliant. That’s why we’ve dedicated ourselves to offering only the highest-quality units and professional installation services.
Made in the USA – Built to Last
All of our CBUs are manufactured here in the United States to meet or exceed USPS “F” Series security standards. Constructed from heavy-duty aluminum and stainless steel hardware, these units are designed to withstand weather, daily use, and attempted vandalism.
Each cluster box unit includes:
- Secure tenant compartments with hardened locks and three keys per door.
- Integrated parcel lockers for package delivery.
- An outgoing mail slot with weather protection.
- A matching pedestal for easy installation.
Available in multiple sizes, door configurations, and colors, our CBUs are a trusted solution for apartments, townhomes, neighborhoods, and commercial developments.
Why Choose Us for Installation?
We know mailboxes.
Unlike many online resellers, we don’t just sell you the unit and walk away. We handle the installation, too. Our team of professional installers knows exactly what it takes to get your CBU set up properly, securely, and in full compliance with USPS regulations.
When you hire us, you get:
- Experienced Installers – Over 10 years in the field.
- Nationwide Service – Wherever you are, we can help.
- Reliable Scheduling – We coordinate installation as soon as your unit ships.
- Job Done Right – Secure anchoring, proper alignment, and USPS-ready.
Our Installation Process
Getting a CBU installed is simple when you work with us:
1. USPS Approval
- Before ordering, your local postmaster must approve the mailbox location.
- This ensures the site is accessible and compliant.
2. Order & Delivery
- Place your order online.
- Your CBU ships directly to you.
3. Scheduling Installation
- As soon as it ships, we contact you to schedule installation.
- If old units need removal, we can provide that service (haul-away not included).
4. Site Preparation
- A level, fully cured concrete pad is required for installation.
- We anchor the unit using either wedge anchors (for existing pads) or J-bolts (if they were installed when the concrete was poured).
5. USPS Activation
- Once installed, contact your local USPS so they can install their master lock and activate the unit for service.
