Installation Notes

Cluster Box Units are regulated by the USPS, so there are a few important steps and requirements before installation:

1. USPS Approval (Required Before Ordering)

   • Your local postmaster or USPS growth manager must approve the location of your new CBU before it’s installed.

   • We strongly recommend getting this approval before placing your order. All CBU sales are final — there are no refunds.

2. Our Process When You Order Installation from Us

   • Your mailbox will ship directly to your address.

   • Once it ships, we’ll contact you to schedule the installation date.

   • After installation, you’ll need to coordinate with your local post office to install the USPS master lock and officially activate the unit for service.

3. Concrete Base Requirements

   • The CBU pedestal must be anchored to a solid, level concrete pad.

   • The pad must be poured and fully cured before installation.

   • There are two anchoring options:

     • Expansion wedge anchors: can be installed on new or existing slabs.

     • J-bolts: installed at the time new concrete is poured, for maximum strength.

4. Removal of Existing Units

   • We can remove old CBUs for an additional cost.

   • Please note: removal does not include offsite disposal. We do not offer haul-away services. If you need haul-away or disposal, you’ll need to arrange that with a separate service.

5. Disclaimers

   • Customers are responsible for securing USPS location approval before ordering.

   • Concrete prep must be completed and ready before our installer arrives.

   • If the site isn’t properly prepared at the scheduled installation time, additional trip or rescheduling fees may apply.
