Salsbury Parcel Lockers 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 and Parcel Locker. If not, we recommend it.

Master Lock Installation

After installing the Parcel Locker according to USPS specs, 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.

Nationwide Mailbox Installation Services

Our Mailbox Installation Service

  • Licensed & Insured
  • Trained Installation pro
  • Available in your area
View Details Below

On our CBU product pages, you will see an option labeled, "Need professional mailbox installation?" By making this option available on the product page, our goal is to be the one-stop shop for your cluster mailbox needs. We offer the following installation options:

Option 1 - Installer mounts pedestal on existing anchor bolts

Typically, you will select this option if you are replacing a CBU where you will reuse the existing anchor bolts embedded in the concrete. The installer will mount the pedestal on the existing bolts and attach the mailbox to the pedestal.

Option 2 - Installer mounts pedestal and installs anchor bolts

In this situation, the installer will drill the anchor bolts into the concrete pad. You will need to procure the anchor bolts beforehand -- you can purchase these directly from us with your CBU order.

Option 3 - Installer removes existing anchor bolts and replaces them

This scenario is similar to Option 2 listed above, with one exception: the installer will remove the existing anchor bolts from the concrete pad prior to installing the new anchor bolts.

Scenarios where this Option may be required:

  • You are upgrading from an older CBU model (Auth-Florence 1575 or NDCBU) where the new CBU pedestal cannot be mounted on the existing anchor bolts.
  • Any situation where the CBU Pedestal cannot be installed over the existing anchor bolts.

Mailbox Installation FAQs

What's included in mailbox installation?

  • Unpacking new CBU mailbox purchased from
  • Installation of CBU pedestal onto the existing concrete pad* via one of the options listed above
  • Mounting CBU box to pedestal

Are your installers licensed and insured?

Yes. We only work with licensed and insured mailbox installers.

Do you offer service in my area?

Yes, unless you are outside the contiguous US. We offer installation services for our customers within the 48 contiguous United States.

Will the installer apply lettering to the mailbox?

No. Installation does not include applying the standard decals supplied with your CBU. You will need to apply the numbers after the unit is installed.

Will the installer remove my old cluster mailbox?

If you are replacing old or damaged cluster mailboxes (pedestal CBU mailboxes), we can ask the installer to remove them from the location as long as we are notified ahead of time. So, if you need the old units removed, please let us know as soon as possible. Please note: an additional charge of $100.00 will apply to your installation service for removal of old cluster mailboxes.

Why should I hire a pro to install my mailbox?

Installing a pedestal mailbox can be complicated. A professional can take care of it more efficiently, saving you time and money.

Will the installer supply any materials I need to secure my mailbox?

No, you need to provide the anchor bolts for this service. Unless you already have anchor bolts, we recommend you purchase anchor bolts with your CBU order. If additional supplies are needed at the site, the provider may be able to supply them at an additional cost. Please also ensure that the location is near a usable power source, if possible.

Will Budget Mailboxes communicate with the installer on my behalf?

Yes. While it is expected that the customer deals with the installer on location, we take it as our responsibility to communicate with the installer on your behalf prior to the appointment. We will also follow up with you to confirm the appointment and any other details.

* It is the customer's responsibility to ensure that the location for installed cluster mailboxes meets USPS requirements. Contact your local post office if you have questions about their specific requirements when installing CBUs at your location.

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


If you don't need USPS delivery and you intend to use the Parcel Locker for private use (where a company or organization will need access to open the master door for delivery), then you need to convert the unit to Private Delivery, which can be purchased as an add-on via the dropdown options section of any Parcel Locker.

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

Optional Anchor Bolts

USPS Approved Mailbox

anchor L-bolts (for wet concrete)

USPS Approved Mailbox

expansion anchor bolts (for existing concrete)

If you need anchor bolts for your CBU installation, add them from the dropdown options above the Add to Cart button.

Question: How do I know if I need anchor bolts?

Answer: You will need anchor bolts to install the CBU pedestal. If you plan to install your bolts immediately after pouring new, wet concrete, then you can purchase the L-bolts. Or, if you plan to install the CBU pedestal into dried or existing concrete, you will need the expansion bolts.

Question: What is the difference between the two different types of bolts?

Answer: The L-bolts for pedestal installation are specifically for installations where new concrete is being poured. For installing your CBU in existing concrete, you will need the expansion anchor bolts for existing concrete.

  • Each bolt kit includes everything required to mount the CBU pedestal to concrete.
  • L-Bolt specs:
  • Expansion Bolt specs:
    • 1/2 inch diameter.
    • 5 1/2 inches long
  • Hardware kit includes four (4) stainless steel anchor bolts and four (4) standard fasteners.

*Note: actual measurements between bolts should be confirmed prior to installation. is not liable for faulty installation due to inaccurate measurements.

Expansion Anchor Bolts Overview

When securing the CBU pedestal to a dried or existing concrete pad, it is critical to use the recommended class of hardware to guarantee the strength and safety of the installation. Galvanized or Stainless Steel masonry anchor bolts (1/2 in. x 5 1/2 in. min. length) are the approved hardware to be used when installing a CBU pedestal to an outdoor concrete location.

When installed correctly and to recommended torque specifications, these bolts create the strongest possible bond while retaining their integrity and tensile strength. However, even the finest hardware can only function as well as it is installed. Please follow the specific guidelines and manufacturer's recommendations when installing these anchors. For an installation tutorial, please review the Installation Walkthrough on this page.

Optional Vandal-Proof Fasteners for Added Security

Vandal-Proof, breakaway fasteners prevent mailbox theft by making it nearly impossible for would-be thieves to remove the pedestal using common tools. How does it work?

After you have successfully installed your cluster mailbox at the desired and USPS approved location:

  1. Apply the breakaway fasteners with a traditional wrench or socket.
  2. The top fastener breaks off after installation, leaving you with an installed fastener with no drive.

Your CBU pedestal will now be permanently secured at your desired location.

** Important: these vandal-proof fasteners are easy to install but very difficult to remove. This is what makes them a High-Security feature. Contact us if you have any questions. **

Color Options

The Salsbury 3302 Parcel Locker is offered in six different color variations: Sandstone, Bronze, Black, Postal Grey, White, and Green.

Sandstone is the most popular color option and is considered the new architectural standard. All finishes are powder-coated and corrosion-resistant. If you need to purchase a different color, simply view the available color options here.

16 Door CBU

Key-Trapping Locks

If you are expecting a package from the USPS, the postal carrier will deliver your package to the parcel locker. Here's how it works:

  • When you get home and check your mail, you would find a key in your CBU mailbox compartment.
  • You would then use this key to open the parcel locker door and retrieve your package.
  • Once you use the key to unlock the parcel locker, it remains securely "trapped" in the lock so that the postal carrier can re-use it when he returns with another 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 the explanation video in this section for more details.

*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. is not liable for faulty installation due to inaccurate measurements.

All Salsbury outdoor parcel lockers 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.

Installation Walkthrough


Here we go over the basics of installing your cluster box into existing concrete. If you plan to install your CBU into new concrete, please see our Installation Manual below.

Note: we recommend you watch the video at the bottom of this section to get an idea of the installation process.

The Pedestal

When you open up the carton for the pedestal, you have a gasket and a template also. Follow the steps below to install your CBU pedestal into the concrete pad:

  1. Locate the center of the pad, put the mounting template down, and then start drilling your holes (using the template).
  2. Drill down at least five and three-quarters with a half-inch drill bit.*
  3. Make sure the surface is clear of rocks and debris.
  4. Once the area is clean, place the gasket down on the concrete (this serves as a barrier between the cement and the pedestal).
  5. Now place the pedestal on top of the gasket. If it's not level, you can add washers to the uneven side.
  6. Once the pedestal is level, you can place your anchors, which are five and a half inches long by one-half inch wide.**
  7. Place the anchors into the holes and torque the bolts down until they're tight using a socket wrench (you can also use an impact wrench to tighten the bolts).
  8. Once you've tightened the bolts, double check that the pedestal is level.

* In the tutorial video, the installer drills down 4-1/2 inches.

** In the same tutorial video, the installer uses anchors that are 4-1/4 inches long. Our anchor bolts are 5-1/2 inches long, according to the manufacturer's minimum requirements.

The Cluster Box

Upon receiving the boxes, open them up to make sure there's no damage. Two people should place the box on the pedestal stand: one person can hold the box while the other person fastens it to the pedestal.

To fasten the box:

  • Inside the box, there will be access plates in the parcel locker(s). Go ahead and slide those out.
  • This will allow you to access the hardware to secure the box to the pedestal.
  • Place the washer on the bolt, followed by the nut. Do this to all four top bolts.
  • Ratchet the nuts with a nine-sixteenths (9/16) socket wrench.
  • Once these bolts are tight, return the access plates you removed from the parcel locker(s) in step one to cover the hardware.

Once complete, close up the box. Now, you will need to contact the post office to send someone to install their arrow locks for USPS access. The postman will install one arrow lock in the outgoing mail slot, and one in each parcel locker.

CBU Care and Cleaning

Care And Cleaning

Cluster Box Units are simple to maintain and clean. Due to the durable nature of aerospace-grade aluminum and the weather-proof powder-coating, these units will resist erosion, scratching and peeling year after year. However, proper care and cleaning will keep your unit looking pristine and prevent environmental buildup.

Basic Mailbox Cleaning

  • Use a soft cloth dampened with a mild detergent or a properly diluted, biodegradable, water-based cleanser such as Simple GreenTM.
  • Avoid using abrasive cleaners such as CometTM or Brillo PadsTM, as they may scratch the surface of your CBU.
  • Simply wipe off the surface from top to bottom to avoid run-down.
  • Rinse with plain water and dry with a clean, soft cloth.
  • Avoid cleaning during extreme temperature conditions.

Regarding a Product's Shipping Estimate

Understanding 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.

Below, we answer the top three FAQs our customers have regarding delivery estimates.


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 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.

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.

Note: 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) 707-0008 . We will provide you with your Order Number and any other details you need.
