Learn more about our estimated shipping and lead times

The lead times listed on this product page represent the best-case scenario for shipping estimates. While we may show that a product "usually ships" within a given period, this period should not be confused with a delivery estimate. Rather, we expect the product to ship from the manufacturer's warehouse within this time-frame.

What does this mean for you? Once you place an order on our site, we begin processing the order with the manufacturer. The processing lead time we list on the product page is the most current estimate from the manufacturer regarding the product.


If you purchase a commercial mailbox from us and decide to cancel because a competitor lists a "faster" lead time on their site, you may be delaying the time it will take to receive your mailboxes.

Why? Because you are placing a new order to be sent to the same manufacturer for processing.


How long will it take to receive my commercial mailbox?

When you order a commercial or cluster mailbox, we process the order with the manufacturer within 1 business day. Once processed, the order usually ships in the time-frame listed on the product page. Since Cluster Mailboxes are large items, they ship via freight carriers. This means that the transit times for these will usually be 5 to 7 business days.

A few things to note about purchasing a cluster mailbox or similar large, commercial-grade product:

  • The freight carrier will call the number you list on the shipping address a day before delivery to schedule a delivery appointment with you.
  • The manufacturer ships using their chosen freight carrier depending on the products ordered and the delivery location.
  • The majority of online retailers who sell commercial mailboxes (CBUs, etc.) ship directly from the manufacturers, just as we do.
  • If you choose professional mailbox installation with your commercial mailbox purchase, please note that same-day installation is not available. Installation will be scheduled after the delivery of your mailbox. In most cases, installation is completed within one week following delivery.

What if I order multiple products from different brands?

If you ordered multiple products, it is possible that they are made by different manufacturers. If this is the case, your products will ship to you separately from each manufacturer.

For example, if you purchase a Mayne Post with a Whitehall Mailbox, your post will ship from Mayne's warehouse in about 3 business days, but your mailbox will ship separately from Whitehall in about 2 to 3 weeks if customized with address numbers.

How can I estimate my shipment's transit time?

Depending on the carrier and your location, transit times will vary. Delivery estimates are best projected using your carrier tracking number. Once your order ships, we'll send you a shipping confirmation email that includes your carrier (FedEx, UPS, YRC, etc.) and tracking number.


If you place an order with us and do not receive an Order Confirmation email, check your spam inbox. If you still do not see an Order Confirmation email in your inbox, contact us right away at (866) 717-4943 . We will provide you with your Order Number and any other details you need.

Aditional Product Options

We Offer Mailbox Installation Nationwide

CBU Mailbox Installation

When selecting the options for your CBU mailbox you will see we offer “Professional Mailbox Installation”. Three choices for installation are offered to make your experience complete for all your CBU mailbox needs.

Option A – Installer uses existing anchor bolts to mount pedestal.

Choose this option if you have existing cluster mailboxes that have anchor bolts that are secure and in good condition and match the footprint of the new cluster mailbox. The installer will then bolt the new mailbox pedestal to the existing anchors and mount the mailbox to the pedestal.

Option B – Installer secures pedestal to new anchor bolts in existing concrete.

Choose this option if you have a concrete pad that is in good condition and does not have anchor bolts. The installer will install the new wedge stud anchor bolts, install the pedestal, and mount the CBU mailbox. Wedge stud anchor bolts can be purchased from The MailboxWorks with your CBU.

Option C – Installer replaces existing anchor bolts.

This is like Option B except that the installer will remove the existing anchor bolts first and then install the new wedge stud anchor bolts.

  • Reasons when this option may be needed:
    • You are replacing an older CBU or NDCBU where the new cluster mailbox pedestal cannot mount to the existing anchor bolts.
    • Any other reason where the cluster mailbox pedestal cannot be installed onto the old anchor bolts.

FAQs for the Mailbox Installation:

What is included with the mailbox installation?

  • Unboxing of your brand new CBU mailbox that was ordered from The MailboxWorks
  • Installing the pedestal onto the existing concrete pad covered by one of the options above*.
  • Securely mounting the CBU mailbox on top of the pedestal.

Do you offer installation in my area?

YES, unless you are outside the continental US. We provide installation services for The MailboxWorks customers in the 48 states of the continental US.

Are your mailbox installers insured and licensed?

YES, our professionals are insured and licensed.

Can my existing cluster mailbox be taken away?

When you are replacing an existing CBU mailbox (pedestal cluster mailboxes) we can arrange to have the installer remove the old CBUs from the job site. We do need to be notified in advance of the installation. There is a charge of $100.00 in addition to the installation service for removal of the existing CBU cluster mailboxes.

Can the installer apply number decals that were ordered loose?

NO, unfortunately you would need to apply any number decals that were ordered loose and not already applied to the cluster mailbox. This is a rare occurrence because number decals are standardly applied to Florence CBU cluster mailboxes. An alternate brand, if ordered, can have decals come loose or if the customer specifies loose decals at the time of ordering.

How do I know if Option A, Installer uses existing anchor bolts to mount pedestal, will work for my cluster mailbox installation?

Measure the distance from left to right using the center of one bolt to the center of the other bolt and verify it measures 10”. Then measure the distance from front to back using the center of one bolt to the center of the other bolt and verify it measures 4”. (see pictures)  If those measurements agree and the bolts are in good condition then Option A should work for you.

Will the installer provide anchor bolts for my cluster mailbox?

NO, you would need to make the anchor bolts available.  If the cluster mailbox is being installed on existing anchor bolts you are all set. Otherwise make it easy and purchase the anchor bolts with your CBU mailbox. If other supplies to secure your cluster mailbox are needed, the installer may be able to provide these at an additional charge.

Does The MailboxWorks coordinate the installation with the installer?

YES.  Before the appointment we coordinate with the installer. We will contact you to coordinate an installation schedule.  Also, the schedule will be confirmed again just prior to the installation along with any pertinent details. The customer would be responsible for meeting with the installer at the scheduled installation appointment. After your install is complete you will receive all the keys for the tenant mailboxes from the installer so that you can hand them out to residents.

Why should I order professional installation service from The MailboxWorks?

A mailbox specialist from The MailboxWorks helps you from the moment you place your order until the installation is complete. We will communicate with your local post office and the professional installers and ensure everything is coordinated.

Installing a CBU mailbox can be a complex process. From knowing how to securely mount the cluster box unit to having the USPS come out and install their locks, the steps can be involved. Our professional installers and The MailboxWorks specialists make the process a snap.

*The customer is responsible for ensuring that the location for the installed CBUs meet the USPS requirements.  Customers should contact their local Postmaster and review the location and any requirements before the installation of the cluster mailboxes at your location.

CBU Mailbox Installation Hardware

Whether you are installing your new CBU mailboxes yourself or having our professional installers do it, we offer two types of anchor bolts as well as optional vandal proof nuts for your cluster mailboxes.

L-Bolt Anchors

L-Bolt Anchors are used when new concrete pads are being poured for your cluster mailboxes. The L shaped anchor bolt is inserted into the wet concrete so that as the concrete sets the bolts are secured in place. If new concrete is being poured, the L-bolt is the best possible CBU mailbox anchoring option. This option comes with 4 stainless steel L-bolt anchors that are 7 inches by 2 inches, 4 washers, and 4 matching hex nuts.

CBU Mailbox Install L Bolt Anchor

Wedge Stud Anchors

Wedge Stud Anchors are used when there is an existing concrete pad that is in good condition and meets postal approval for cluster mailboxes. A hole is drilled into the concrete and the anchor bolt is inserted. Then as the nut is tightened and the anchor is pulled up, the base expands for secure holding of your CBU mailbox. This option comes with 4 stainless steel wedge stud anchors that are ½ inch wide and 5 ½ inches long, 4 washers, and 4 matching hex nuts.

CBU Mailbox Installation Stainless Stud Anchor

Tamper-Resistant Nuts

Upgrade your installation hardware by including two optional tamper-resistant nuts to prevent your CBU cluster mailbox from being stolen. The nut is easily installed using a standard socket or wrench. The hex head breaks away upon tightening and leaves a non-removable cone. Tamper-resistant nuts install easily but are hard to remove. The set of 2 stainless steel tamper-resistant nuts should be installed kitty corner from each other in order to deter theft.
