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.

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.

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.

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.

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 four and a half inches 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 four and a quarter 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.

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

You can use a soft cloth dampened with any mild detergent or a properly diluted biodegradable, water-based cleaner (e.g., Simple Green) to clean the surface of all clear aluminum or powder coated commercial mailboxes.

Basic cleaning

  • Wipe off the surface from top to bottom to avoid run-down.
  • Avoid using abrasives, which can damage the mailbox surface.
  • Rinse with plain water and dry the surface.
  • Avoid cleaning during extreme temperature conditions.

Advanced cleaning

  • To varying extents depending on the color, you may be able to remove some spray paint or marker applied graffiti from your CBU’s exterior by using a stronger cleaner like Krud Kutter or a mild petroleum-based solvent like mineral spirits.
  • Test a small, less noticeable area on the CBU first, a few seconds at a time. Do not allow the chemical cleaner to remain on the surface for an indefinite period, as this could damage the CBU’s exterior coating.
  • Remove any residue using a mild cleaner, and then rinse with plain water.

Touch up paint for CBUs

In some cases, you may be able to find a matching touch-up paint for your CBU’s powder-coat finish. We sell a touch-up paint pen and a touch-up paint spray in Postal Grey for the Auth-Florence cluster box. For all other colors, please call us at (866) 707-0008 or open a chat online, as we will need to check directly with the manufacturer to confirm availability and place a special order for the needed touch-up paint, if available.

Cleaning your CBU hardware

If a mailbox lock or door mechanism becomes clogged with ice due to extreme winter conditions, the lock manufacturer suggests using Tri-Flow Superior Lubricant Aerosol.

  • Spray this lubricant directly into the keyhole and onto the key.
  • Slide the key in and out of the lock several times to spread the lubricant.
  • Do not apply too much product, as a small amount is sufficient.
  • Wipe off any excess lubricant from the lock and key.
