12 Tenant Cluster Box - 1 Parcel Locker

Introducing the new “F” Series Cluster Box Unit (CBU) — designed to meet or exceed USPS security standards. Constructed of heavy-duty aluminum with stainless steel hardware, these high-security units are USPS approved and include a matching pedestal. Access is from the front through two easy-opening master doors with built-in hold-open devices for convenience and safety.

Installation Notes

Before ordering or installing, please review the following requirements:

1. USPS Approval (Required Before Ordering)

   • Your local postmaster or USPS growth manager must approve the location of your new CBU.

   • We strongly recommend securing approval before purchase. All CBU sales are final — no refunds.

2. Our Process When You Add Installation Service

   • Your mailbox will ship directly to your address.

   • Once shipped, we’ll reach out to schedule installation.

   • After installation, USPS will install the master lock and activate the unit for service.

3. Concrete Base Requirements

   • CBUs must be anchored to a level, fully cured concrete pad.

   • Anchoring options include:

     • Expansion wedge anchors for new or existing slabs.

     • J-bolts installed at the time new concrete is poured.

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 provide haul-away services. If disposal is required, this must be arranged with a separate provider.

5. Disclaimers

   • Customers must obtain USPS approval before ordering.

   • Installation requires the site to be properly prepped (concrete pad poured, level, and cured).

   • Additional fees may apply if the site is not ready when installers arrive.
