USPS Approved and Ready

USPS Approved Mailbox

Salsbury CBU’s are Pre-approved

Pre-approved by the USPS, cluster mailboxes are considered the industry standard when it comes to outdoor, centralized mail delivery.

Installation Location

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.

Master Lock Installation

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.

The Regency™ Decorative Cluster Mailbox2

Salsbury’s Regency Decorative CBUs include the standard CBU along with the 1) decorative finial crown cap and 2) the rounded pedestal cover. The decorative top and pedestal covers are made of high-grade, die-cast aluminum. The decorative top easily attaches to the CBU and includes a 3-inch diameter ball finial. Likewise, the decorative pedestal cover attaches over the included CBU pedestal and comes with all the needed installation hardware for assembly. Regency Decorative CBUs are accessed from the front by way of two (2) easy-opening master doors. Like the standard Salsbury units, these decorative models feature a durable powder coated finish available in five (5) contemporary colors. Minor assembly is required.

5 Year Product Warranty

All cluster box units (CBUs) sold on BudgetMailboxes.com come with a Five (5) Year Warranty.

New USPS Standard

USPS Approved Mailbox

Obsolete: NDCBUs are no longer permitted for replacement or new installations

USPS Approved Mailbox

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the new cluster box unit specification (right image) became the standard for all manufacturers and replaces both the outdated Neighborhood Delivery Collection Box Unit (NDCBU) and the “E” series CBU.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 These outdated units fall into disrepair as they age and are, in many cases, quite dilapidated.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.

16 Door CBU

CBU High-Security Standards

BM Lock

All CBUs are designed to deter mail theft attempts using the following features:

  • All units are made of high grade, industrial, aircraft-quality aluminum.
  • On the outside of the unit, there are no removable fasteners. This prevents tampering.
  • The cabinet is made using high-precision robotic welding.
  • The CBU uses a sloped roof for water run-off and a drip-edge in the front to protect the individual slots from rainwater.

    Drip Edge
  • The master-loading door has a vertical bridge with an overlap that eliminates the gap between the two master-loading doors -- in other words, there are no pry-points on the unit.

    No Pry Point
  • Heavy-duty, zinc-plated cam locks are tamper proof and latch through the aluminum frame for added security.

    Cam Lock
  • The outgoing mail slot uses a sloping hood to prevent a person from reaching in with their hand.

    Sloped Hood
  • The aluminum, anti-fish comb deters thieves from reaching into the slot with coat hangers or other prying tools.

    Anti Fish Comb

Don’t need USPS delivery? Convert to private use.

USPS

If you don’t need USPS delivery and you intend to use the CBU for private use (where a company or organization will need access to open the master door for delivery), then you need the Postal to Private Conversion Kit, which can be purchased via the dropdown options section of any CBU.

Under the Option labeled “Will the USPS be delivering to this mailbox?”, select “No, this box is for private use…”. Private delivery CBUs are typical where mail delivery is handled by private distribution within the company or organization.

The Cluster Box Units technical specification is what is known as a 4C Horizontal Mailbox, which is the current USPS Standard for centralized mail delivery. Under 4C regulations, the tenant boxes are wider so that all mail, including larger envelopes and magazines, can be delivered flat without any folding. There is also enough room in each tenant box for small-sized parcels.

Integrated Parcel Lockers

Integrated Parcel Lockers

Among the many benefits of the CBU are the integrated parcel lockers for package delivery. If you receive a parcel, the Postal Carrier will conveniently leave the key to the parcel locker in your mailbox so that you can retrieve your package.

Security Tip: Once you enter the key and open the parcel locker the key cannot be removed. This is by design so that only the postal carrier can remove the parcel locker key.

The Matching CBU Pedestal - Easy Installation

The matching CBU Pedestal - Easy Installation

*Disclaimer: the CBU anchor bolts, nuts, and/or vandal proof nuts for pedestal installation are specifically for installations where new concrete is being poured. Actual measurements between bolts should be confirmed prior to installation. BudgetMailboxes.com is not liable for faulty installation due to inaccurate measurements.

All Salsbury cluster mailboxes include an easy-to-install pedestal. The CBU Pedestal is constructed of heavy-duty, corrosion-resistant aluminum. Cluster mailboxes can be mounted on the included pedestal (or a base of your choice provided it meets USPS height specifications).

The pedestal comes with the needed stainless steel hardware for 1) mounting the pedestal to the cluster box and 2) mounting the unit to the concrete slab (using standard bolts). If you need to purchase anchor bolts for installation prior to pouring the concrete slab,* you can add these via the dropdown options above the Add to Cart button.

The CBU concrete pad spec sheet for installing the pedestal is below.

Benefits of the CBU

Benefits of the Cluster Mailbox

The benefits of centralized mail delivery:

1. Value - It costs less to install per resident than individual curbside mailboxes. Also, mail delivery can often begin even before residences are occupied.

2. Community - CBUs can help build stronger neighbor relationships and trust as residents meet and talk while retrieving their mail.

3. Safety - Highly visible centralized mail centers are safer than isolated delivery locations for residents and help provide greater protection from mail theft and mailbox vandalism.
