Wide Tenant Boxes Accommodate Larger Envelopes and Magazines
September 21, 2020
Five Year Warranty
All cluster box units (CBUs) sold on BudgetMailboxes.com come with a Five (5) Year Warranty.
Florence Manufacturing provides a five (5) year Warranty on its products from the date of purchase from an Florence Mailboxes Dealer (i.e., BudgetMailboxes.com). For more info, refer to the Florence Mailboxes Warranty sheet.
Likewise, Salsbury Industries covers defects in material and workmanship if reported in writing to them within five (5) years of the delivery date for CBUs. Refer to the Salsbury Warranty sheet for more details.
CBU High-Security Standards
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.
-
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.
-
Heavy-duty, zinc-plated cam locks are tamper proof and latch through the aluminum frame for added security.
-
The outgoing mail slot uses a sloping hood to prevent a person from reaching in with their hand.
-
The aluminum, anti-fish comb deters thieves from reaching into the slot with coat hangers or other prying tools.
Wide Tenant Boxes Accommodate Larger Envelopes and Magazines
The Cluster Box Unit's tenant compartment size 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.

Shown above: the 13 Door CBU Tenant Box (4 - ¾ in. high)
The 13 Door CBU - Larger Tenant Boxes
Whereas the tenant boxes are three (3) inches high on the 8, 12, and 16 Door CBUs, the 13 Door CBU boasts larger boxes at 4 - ¾ inches high. These are considered "B" size doors whereas the standard units come with the "A" size, or 3-inch high doors. If you need tenant boxes to accommodate larger deliveries, the 13 Door CBU may be the right choice for your specific application.
Four (4) Large Tenant Doors
The 4 Door CBU Mailbox with Extra Large Tenant Doors (1570-4T5) is designed for residential and commercial developments as well as for businesses. It makes use of four (4) large mail slots for that extra room retailers and other commercial businesses need for their incoming and outgoing post, as well as two (2) large parcel lockers to securely hold package deliveries. The incoming mail slot dimensions are: 6 - ½ inches High x 12 inches Wide x 15 inches Deep.
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. See video explanation below:
Extra Parcel Lockers
The Florence Mailboxes 8 Door CBU with 4 Parcel Lockers (1570-8T6) features two (2) additional parcel lockers compared to the standard 8 Door CBU. While the box size is the same as a 16 Door CBU, the extra space is used for the added parcel lockers. This may be the right application for you if the USPS makes frequent parcel and package deliveries to your location, or if you are looking to save space by featuring more integrated parcel lockers rather than stand-alone parcel lockers.
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 installat on. BudgetMailboxes.com is not liable for faulty installation due to inaccurate measurements.
All 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 into new concrete is below.
For more details on pedestal installation, see our Installation Walkthrough.
Heavy-Duty Cam Lock
Every tenant door on the Cluster Box Unit features a stainless steel heavy-duty five-pin cylinder cam lock with a dust and rain shield, along with three (3) keys. This simple yet effective locking mechanism provides the needed security to keep your mail safe until you retrieve it.
If you ever need to replace one of the cam locks, the process is very straightforward. Watch the video below to see how you can replace one of these locks within minutes.
Benefits of the CBU
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.
