Cluster Box Units (CBU) – Neighborhood Security CBU Mailbox

C.B.U.s (Cluster Box Units)

Our CBUs (Cluster Box Units) are all custom and completely welded out of a 1/4″ steel frame with 3/16″ steel-reinforced doors. There are no rivets or spot welds, or parts that can be removed. The shell is over 3-4x thicker than the next heaviest duty CBU on the market! If you would like a quote, we need to know:

Number of Total CBU Units needed (Complete CBU location)?
One location or multiple locations available?
Number of Total Tenants/homes needed (individual slots)?
Need of Outgoing Mail?
Do you need Larger Package Compartments?
Do you need an in-Ground Post (Dirt area), OR a Surface Mount Post (An existing sidewalk)?
Zip code for shipping?
Is the delivery location a residence, OR is it a commercial address?
Do you have access to a forklift or a loading dock?

CBUs are very heavy and the lightest CBU will be approximately 250 lbs., and then go up from there. They also require front and rear door access — one side for the mail carrier and another for the tenants. You will need USPS approval for this setup.

When Will Your Mailbox Ship?

Because of custom options, we don't keep a huge inventory of mailboxes. If your mailbox is in stock, it will ship within a few days. Otherwise, here are our average shipping times*:

Smaller Mailboxes (M1-LT, Small & Large): 1-2 weeks
Larger Mailboxes (Fortress, Vacationer, Senator & Package box): 2-3 weeks
The Vaults & CBUs: 4-6 weeks
Smaller accessories ship within 2-3 days
Custom Colors will add 1 week to the above time frames
Extra keys can take 7-10 days for delivery

*Larger quantities or custom orders will take longer.

Most Products Ship FedEx

Our mailboxes except for the Package Box & Vaults, and accessories ship FedEx.

If you order a quantity of 4 or more larger items (Mailboxes and Posts), your order will ship FedEx.

Shipping for FedEx can be calculated at checkout. If the total weight of your order is higher than what FedEx allows, the freight option will appear. If that happens, we will call and finalize the cost for freight shipping once your order has been placed.

Large Items & Larger Quantities Ship Freight

Our Package Box, All Vaults, and Racks must ship freight.

Order quantities of 4 or more mailboxes will ship freight. One exception is the M1-LT -- we've shipped 10 FedEx ground and it's cheaper than freight.

The T-Post for 3 generally ships freight. We can make the T-Post for 3 in two pieces (Not all welded together) and ship it FedEx ground if you want. We do this often, but it's after asking your opinion.

We will call and finalize the cost for freight shipping once your order has been placed.
