Pre-approved by the USPS, cluster mailboxes are considered the industry standard when it comes to outdoor, centralized mail delivery.
If you are involved in a new construction development, you have probably already consulted or will consult with your local postmaster regarding the placement (location) of your CBU. If not, we recommend it.
After installing the CBU, follow-up with your local post office and the USPS will install their master lock for the main access door. Note: the USPS provides the master lock and only they have the keys to it.
Obsolete: NDCBUs are no longer permitted for replacement or new installations
New CBUs accommodate both mail and packages while providing greater security.
Developed and approved by the USPS in 2005, the new cluster box unit specification (right image) became the standard for all manufacturers and replaces both the outdated Neighborhood Delivery Collection Box Unit (NDCBU) and the “E” series CBU.
While the original NDCBU introduced convenience for residents and letter carriers alike, it is no longer permitted for replacement or new installations. These outdated units fall into disrepair as they age and are, in many cases, quite dilapidated. The newer 2005 specifications boast a thoroughly tested design that provides better security and durability over time.
If you need anchor bolts for your CBU installation, add them from the dropdown options above the Add to Cart button.
Answer: The CBU anchor bolts, nuts, and/or vandal proof nuts for pedestal installation are specifically for installations where new concrete is being poured.
*Note: actual measurements between bolts should be confirmed prior to installation. BudgetMailboxes.com is not liable for faulty installation due to inaccurate measurements.
The 8-Door CBU includes two (2) fully integrated parcel lockers and a matching pedestal. One additional compartment is labeled "Outgoing Mail" and includes a weather protection flap and an 12 in. W x 3 in. H mail slot.
The CBU also features individually numbered mail compartments and a mail carrier access door for USPS provided master arrow lock.The unit itself is constructed of high-grade, heavy-duty, aircraft aluminum while the hardware is constructed of stainless steel. All CBUs on BudgetMailboxes.com are manufactured here in the USA.
