4C Pedestal Mailbox Applications
Florence Manufacturing’s new 4C series commercial mailboxes are designed to meet the updated USPS regulations that have stricter security standards.
USPS Approved Outdoor Pedestal Mailboxes
In 2006, USPS implemented the Standard-4C regulation (STD-4C) that requires that all post mounted or pedestal mounted commercial mailboxes installed as part of a major renovation (or new construction project) meet 4C requirements for the sake of security and accessibility.
In compliance with these laws, all Florence 4C Pedestal mailbox units are approved for use by USPS. Please note that you must still receive local Postal permission for installation and usage of 4C pedestal mailboxes.

Frequently Asked Questions
Who do I contact regarding the placement location of a new or replacement 4C pedestal mailbox?
Contact your local postmaster to determine where to install your new commercial mailbox, as well as details on what cluster mailbox unit is needed for replacement. Do not contact your local letter carrier.
What is the difference between a 4C pedestal mailbox, a recessed 4C mailbox, and a surface mount 4C mailbox?
Pedestal mount mailboxes have a finished cabinet enclosing the 4C mailbox unit plus a pedestal stand. The pedestal stand can be affixed to a concrete slab for any outdoor installation.
Recessed mount mailboxes are installed indoors into a rough opening in a wall that is made to fit the exact length, width, and depth of the mailbox unit.
Surface mount mailboxes are installed indoors on a flat wall surface.
Why does the 4C Pedestal mailbox require local postal approval?
While 4C mailboxes are postal approved, their installation on a pedestal does require approval by your local Postmaster for your particular application. It’s also a good idea to review the installation location with your local postmaster as well.
I’ve noticed that 4C pedestal mailboxes have a longer ship time than CBU mailboxes. Why is that?
4C pedestal mailbox units are custom made to order, which requires additional lead time at the manufacturer’s level. CBU mailboxes are pre-made and ready to ship to the buyer as soon as the order is place.
MOUNTING 4C PEDESTAL MAILBOXES
Can I mount the 4C mailbox on an existing pedestal?
We do NOT recommend this. Old or used pedestals may not be as strong or have corrosion issues, which could cause the 4C mailbox to collapse. The 4C mailbox unit can weigh up to 240 lbs and needs to be properly supported. Using an old pedestal can cause potential danger to your USPS mail carrier, tenants, and innocent bystanders.
Can I mount the 4C mailbox on a pedestal other than the factory-supplied pedestal?
We do NOT recommend this. The pedestals that come with 4C mailboxes are specifically designed to support the 4C mailbox unit. Should you decide to use a different mounting method or pedestal (other than the factory supplied pedestal and instructions) you need to obtain approval from your local USPS Postmaster.
Can I adjust the height of the pedestal 4C mailbox during installation?
No. 4C pedestal mailboxes must be installed at the exact height requirements as specified by the USPS.
Do I need to contact my local USPS before installing a 4C Pedestal Mailbox?
Yes. Contact your local Postmaster before installing your 4C pedestal to get authorization for the use of a 4C mailbox unit on a pedestal and to review the installation location.
Does my 4C pedestal mailbox come with everything needed for installation and usage?
Based on USPS requirements/requests, there are two additional items required for your 4C pedestal mailboxes that are not included with your purchase:
- USPS Arrow Locks – installed on outgoing mailbox door and parcel locker doors.
USPS does not allow factories or any non-USPS employees to possess these master locks. Once you have your 4C pedestal mailbox unit installed you will need to contact your local USPS to request that they come and install the USPS Arrow Locks. Typically, they do not charge for this service.
- Anchor Bolts – used for mounting the 4C Pedestal mailbox to concrete, which requires 4 bolts per unit. USPS requests that The MailboxWorks and other mailbox distributors do not include concrete mounting anchor bolts because there is too much variation in each individual installation. Please refer to our 4C Pedestal Installation Instructions to determine the anchor bolts required for your mailbox installation. The factory recommends that you use ½-inch diameter L-Bolts and a range of expansion anchor bolts outlined in the instructions. For most applications, you can purchase the L-bolt anchor bolt kit at The MailboxWorks and any expansion anchor bolts at your local hardware store.
Help! I can’t find the tenant keys (or mounting hardware and installation instructions) for my new 4C Pedestal mailboxes?
You should find all the keys, mounting hardware, and instructions tucked carefully inside the mailbox cabinet. In order to access these, you need to:
- Take the 4C mailbox module out of the box and set it on a workbench.
- Open outgoing mailbox door (located below the outgoing mail slot on the right-hand side).
- Carefully push up on latch on the left side of the inside of the outgoing mailbox compartment (your 4C mailbox will be top heavy).
The right side of the 4C cabinet will open and there will be a latch on the left side of the cabinet to open completely. You will find all the keys, hardware, and instructions in the lower left hand compartment.
Why did my 4C pedestal mailbox not come with anchor bolts?
USPS requests that we do not provide anchor bolts as each individual mailbox installation varies. The MailboxWorks sells the basic J-bolts but you will need to refer to 4C Pedestal Installation Instructions by the USPS to determine what expansion bolts you will need to purchase at your local hardware store.
Why is there no lock on the 4C pedestal outgoing mailbox?
By regulation, USPS must install these master locks, which are called “Arrow Locks.”
4C PEDESTAL MAILBOX SHIPPING AND DELIVERY
How are 4C pedestal mailboxes shipped?
The MailboxWorks ships all 4C pedestal cluster mailboxes (regardless of model number or number of doors) in two boxes:
- One box contains the pedestal, which is approximately 25 lbs.
- One box contains the 4c mailbox model, which ranges from 56 – 225 lbs depending on the mailbox unit size.
We recommend that upon delivery you confirm you have received the right number of shipping boxes and that the number of boxes agrees with the box count on your delivery receipt provided by the freight company.
What if one of my 4C pedestal mailbox parcels or boxes appears to be damaged upon delivery?
Carefully inspect and report any damaged shipping boxes to the delivery person before signing for the delivery of goods. If you notice significant damage you can refuse delivery of the item. We recommend only refusing delivery of the one damaged item and not the entire shipment. Should this occur, please contact The MailboxWorks as soon as possible.
What if I notice damage of shipping boxes after the delivery person has left?
In the case that you only notice damage after you sign for the 4C pedestal mailboxes, please contact The MailboxWorks at 1-800-824-9985 as soon as possible. We recommend taking pictures with your camera to document the damage for the factory and delivery company’s records. Please note that we can best address the issue if you alert us right away.
4C Mail Slots
How big is the outgoing mail slot on 4C pedestal mailbox units?
The outgoing mail slot is 3/4”H x 12”W.
Does the outgoing mail slot on the 4C pedestal mailbox unit offer theft protection?
Yes, there is an aluminum comb on the outgoing mail slot that helps prevent mail fishing and the removal of outgoing mail.
Can I remove the outgoing mail slot?
No. The mail slot and compartment cannot be removed from the 4C pedestal mailbox unit.
Can a USPS 4C mailbox be customized with a private mail slot?
No. Only the USPS can place items in 4C pedestal mailboxes that are serviced by the USPS. Adding your own private mail slots can compromise the security of the mailbox unit and enable mail fishing.
4C Pedestal Locks and Keys
I just received my new 4C pedestal mailbox but can’t find the keys. Where are they?
Keys for 4C pedestal mailboxes with parcel lockers: All 4C pedestal mailbox keys, hardware, and installation instructions are in the left side parcel locker. To open, reach into the center of the unit and push up on the bracket located in the upper left corner. This will open the right-side gate and allow you to open the left-side gate and give access to the left side parcel compartment.
Keys for 4C pedestal mailboxes without parcel lockers: All 4C pedestal mailbox keys, hardware, and installation instructions will be found in one of the tenant door compartments.
NOTE: Before completing the following steps ensure that the 4C cluster mailbox unit is securely placed on a flat surface so that it doesn’t fall over when the master front door is open.
How do I get a master door lock for my 4C pedestal mailbox?
Once you have installed the mailbox unit contact your local post office to come install the master lock(s) on your new 4C pedestal mailbox: this can only be done by the USPS.
Do mailbox locks come installed in the 4C pedestal mailbox tenant doors upon delivery?
Yes. All 4C pedestal mailbox locks come with locks installed and with 3 keys for each tenant mailbox lock.
Can I get more than just 3 keys for a tenant door?
You can order up to 6 keys per tenant door if you need more than the standard 3 keys that come with the 4C pedestal mailbox units. Please contact our customer service team by phone at 1-800-824-9985 or by email to discuss this option.
Additional tenant mailbox door keys cost around $3.00, depending on quantity volumes.
How do I order additional tenant keys after purchasing a 4C pedestal mailbox?
Contact The MailboxWorks to purchase additional blank keys that you can take to any locksmith or hardware store to have cut. Please note that the locks and key blanks on all 4C pedestal mailboxes are proprietary and are difficult to source through hardware stores and locksmiths. We’d be happy to source these for you!
When ordering, please have the original key(s) available as there are two key blank types used by the manufacturer. You will find a four-digit number on the key followed by “PS”. Examples include:
- 1000PS – 1999PS
- 2000PS – 2999PS
- 3000PS – 3999PS
- 4000PS – 4999PS
Typically, Florence Mailboxes, the 4C pedestal mailbox manufacturer, will use the same key blank for the 4C cluster mailboxes but it is not always possible, especially for larger orders. Please check each key before ordering any key blanks.
Can I order new locks for tenant mailbox doors?
Yes. There are several reasons you may want to do this:
- A tenant moves out
- Keys for a lock are lost
- Keys for a lock are stolen
If you need to order new locks for your 4C pedestal mailboxes please contact The MailboxWorks.
The outgoing mailbox door on my 4C pedestal mailbox doesn’t have a lock. What should I do?
USPS can only install this USPS Arrow Lock upon your request. Please contact USPS for installation. Typically, they do not charge for this service.
4C Pedestal Mailbox Door Identification
How many characters can be engraved on the tenant mailbox doors?
You can engrave up to 12 characters per line and up to 2 lines.
What size of numbers can be engraved on the mailbox doors?
All engraved characters are ¾” tall.
What size of decals are used for mailbox door identification?
All mailbox door decals are 1 ½” x 1 ¾”.
How many characters fit on a decal?
Up to 5 characters.
4C Pedestal Parcel Lockers
What is a parcel locker?
Parcel lockers are the part of a 4C pedestal mailbox used for package delivery to store oversized packages that do not fit into individual tenant mailbox compartments.
How does package delivery to a parcel locker work?
Should a tenant receive a package that does not fit into their individual tenant mailbox compartment the USPS mail carrier puts a key tag and instructions in the tenant’s mail slot and secures the package in one of the parcel lockers. The key tag and instructions give the tenant/recipient access to the larger parcel locker. All the tenant needs to do is open the corresponding parcel locker with the provided key and remove their package. Once the key is inserted into the parcel locker lock it cannot be removed and stays in place until it is retrieved by the mail carrier.
What is a captive lock?
4C pedestal mailboxes have a captive lock on all parcel lockers, which means that once the key is inserted it can only be removed by the authorized mail carrier on their next visit.
Can I use the parcel locker as an extra tenant mailbox?
No. Parcel lockers have a captive lock and do not work the same as tenant mailboxes. Furthermore, USPS regulation restricts 4C parcel lockers from being removed, changed, or modified for any other purposes other than parcel delivery by the USPS.
Does the USPS require parcel lockers?
Yes, all locations with 10 or more cluster mailbox compartments require a parcel locker. At their discretion, your postmaster may approve a 4C pedestal mailbox with no parcel locker in the case that an alternate secure receiving facility is available (such as a separate bank of parcel lockers).
Do all 4C mailboxes come with parcel lockers?
No. There are also 4C pedestal mailboxes without parcel lockers for units with less than 10 tenant doors that do not require a parcel locker. Larger 4C cluster mailboxes without parcel lockers are available for locations that have a USPS approved alternate secure receiving facility.
4C PEDESTAL MAILBOX REPLACEMENT PARTS AND ACCESSORIES
Can I order replacement doors and door pins for the 4C pedestal mailboxes?
Yes, we sell replacement doors and hinge rods/pins.
Can I buy a sign holder to attach to the 4C pedestal mailboxes?
We have been asked if we sell plexi sign holders to attach to the 4C pedestal mailboxes to house various notices that typically get attached to the side of cluster mailboxes. Unfortunately, we do not sell these at The MailboxWorks.
Can I buy other parts for my 4C pedestal mailboxes?
Yes, you can view the available 4C cluster mailbox parts we have online here.
Additionally, if you need help finding other commercial mailbox parts please call us at 1-800-824-998 for assistance.
What does Centralized Mail Delivery Mean?
Centralized mail delivery is a form of mail delivery where a local mail carrier delivers and collects mail at one central mailbox unit rather than to each individual residence.
What are the benefits of centralized mail delivery system to 4C pedestal mailbox units?
Whether it is a single-family subdivision or a multifamily or office complex, 4C centralized mail delivery improves mail delivery services. Mail is delivered to a convenient central location. USPS mail carriers are able to make multiple deliveries with just one stop, which results in faster service, lower fuel consumption, and lower carbon emissions.
Can 4C pedestal mailboxes be used as a Centralized Mail Delivery System?
4C pedestal mailboxes are “clustered” style community mailboxes designed for centralized mail delivery. This includes 4C mailboxes (or cluster box units), which are free-standing and mounted on a pedestal, plus other types of STD-4C compliant cluster mailboxes that are mounted on (or in) a wall, a kiosk, or an outdoor mailbox shelter.
Does the pedestal 4C mailbox need to be USPS approved?
All centralized mailboxes serviced by the USPS, including 4C pedestal mailboxes, must be USPS approved. This means the community mailboxes have gone through rigorous testing and approval prior to being sold in the marketplace. Your local Postmaster must first approve any 4C mailbox installed on a pedestal.
Do I need centralized mail delivery?
Check with the local Postal Authorities early in your construction project for your new residential or commercial development. Ask about the mail delivery plan required by the U.S. Postal Service for your planned project.
Do I need a STD-4C compliant mailbox system?
Yes, as of October 5, 2006 all new construction and major renovation projects require the new “4C” postal standard mailbox units that are U.S. Postal Service compliant.
What makes the new STD-4C compliant mailbox system different?
The USPS changed several factors with the new STD-4C compliant mailbox system:
- Mailbox Shape – the traditional cube style mailbox compartments have been updated to flatter style horizontal compartments. The new minimum size requirement is 12′′w × 15′′d × 3′′h.
- Parcel Storage – the new 4C mailbox units incorporate a fully integrated (or stand-alone) parcel locker option. A minimum of one parcel locker per 10 tenant mailbox compartments is required.
- Mailbox Security – the new 4C mailboxes have strengthened security requirements for the entire mailbox receptacle and an improved, standardized tenant mailbox compartment lock design.
- ADA Compliant – the new STD-4C mailbox systems also meet the requirements of the Americans with Disabilities Act (ADA).
Please Explain What the USPS-STD-4B+ Standard Means?
The United States Postal Service (USPS) developed the USPS STD 4B+ standard in an effort to improve mailbox security by strengthening and improving the arrow lock compartment of the mailbox master door. This standard is applied to vertical commercial mailboxes (such as the Florence model 1250), as well as apartment complex mailboxes such as the horizontal style Florence 1400 series mailboxes. You can find Florence 4B+ mailboxes here.
How do the new regulations affect what type of centralized mailbox I buy (4C or 4B+)?
Ask yourself these three questions to determine what type of community mailbox system the USPS requires for your project:
- Is the mailbox being used for new construction?
a) If yes, only 4C rated mailboxes or freestanding CBU or 4C pedestal mailboxes must be used.
- If renovating, will the new mailboxes be used as replacements in the same rough opening (RO)?
a) If yes, then 4B+ rated vertical or horizontal mailboxes can be used.
b) If you are adjusting the RO, 4C rated mailboxes must be used. If you are limited on wall space you may consider mounting CBUs or 4C mailboxes outside. Always consult your local Postmaster about placement location.
- Is the community mailbox installation inside or outside?
If installed inside, any community mailbox model can be used depending on your answer to question 1a and 2a/b above.
If installed outside (and unprotected), install CBUs, 4C mailboxes, or 4C pedestal mailboxes, as the 4B+ mailboxes are NOT rated for outside use.
How were the USPS standards set?
The United States Postal Service first studied various factors like mail size, the volume of mail received, the mail delivery system efficiency, and other things such as mail theft and vandalism. These factors, along with forecasting the future needs of efficient mail delivery, helped the USPS to create an Apartment Consensus Committee that could review the findings and make more informed decisions about community mailboxes. This committee included representation from mailbox manufacturers like Auth Florence Manufacturing, plus mailbox service providers, resellers, property management companies, and owners, as well as members of the USPS. Following a year of meetings and discussions the committee agreed on a set of new mailbox requirements. These STD-4C regulations are now mandatory for centralized mail delivery systems serviced by the USPS.
What is the purpose of the new 4C standards?
Ultimately, the regulations are designed to improve mail service.
Will mailbox regulations change again soon?
Prior to the October 2006 change in regulation, the USPS last revised mailbox standards in 1975. These previous standards were used for 30 years and were effective for the drastic increases in mail delivery during that period. It is not easy or quick to change mailbox standards and the USPS aims to ensure these new mailbox standards will protect and manage future mail trends.
How can I tell if a mailbox meets the USPS requirements?
4C mailbox manufacturer Florence Manufacturing, places a USPS Approved Logo on each mailbox product that meets these STD-4C mailbox requirements. At The MailboxWorks, we offer an extensive range of USPS approved community mailbox products. Our customers can shop the versatile 4C mailbox suite collection to mix and match 4C modules for the perfect configuration. Prior to starting, we encourage you to check with your local postmaster about mailbox requirements and any changes to your building’s mail delivery system.
Where is the manufacturer’s name on the mailbox?
You can find the manufacturer name on the front of the mailbox unit, typically on the Outgoing Mail door or in one of the bottom corners.
