NATIONWIDE DELAY
TIMING & EXPECTATIONS ARE EVERYTHING
UPDATE: January 11,2023
Florence Corporation is experiencing delays of up to 2 weeks for Cluster Mailbox orders due to overwhelming demand.
This affects all online mailbox distributors & retailers.
Regarding a Product's Shipping Estimate
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 timeframe.
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.
Note
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 with the same manufacturer for processing.
Below, we answer our customers' top three FAQs 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 one 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. As such, these transit times will usually take 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.
Most (if not all) 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 unavailable. We will help you schedule the installation after the
delivery of your mailbox. In most cases, our installers complete the installation within one week following delivery.
What if I order multiple products from different brands?
If you order multiple products, you may be purchasing products from different manufacturers. If this is the case, your products will ship to you separately from each manufacturer.
For example, if you purchase a set of wedge anchor bolts with a cluster mailbox, your CBU will ship from Florence or Salsbury's warehouse in about 5-7 business days. Still,
your anchor bolts will ship separately from another warehouse in about 1 to 3 business days.
How can I estimate my shipment's transit time?
Depending on the carrier and your location, transit times will vary. You can estimate delivery times 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 immediately at
(866) 707-0008 . We will provide you with your Order Number and any other details you need.

How to Build Your Sign System
Configuring the Imperial Estate system takes five decisions. Work through them in order and you'll have a compatible, complete setup before checkout.
Choose component color. Black is the standard HOA and campus choice. It holds up against UV fading better than lighter powder coats and coordinates cleanly with most architectural palettes.
Choose your traffic sign and blade combo. Pair your STOP face with a street name blade. The style of the blade frame influences the overall look of the sign and how the name panel is attached. Flat blades suit minimalist installs; framed blades add structure.
Select pole height. Measure from finished grade to the bottom of the sign face. MUTCD recommends a minimum 7-foot clearance at pedestrian locations and 14 feet at vehicle crossings. Subtract the depth going into the ground from the total pole length to find the height above ground.
Pick frame size and blade frame style. Frame size determines how many street name blades you can mount. Blade frame style, open or closed, changes the visual weight of the assembly. Open frames read lighter; closed frames look more formal.
Choose finial and base. The finial caps the top of the pole and signals a planned installation rather than a utility setup. The base choice affects durability: a decorative flange base works well on poured concrete pads, while direct burial suits softer ground installs.
Compliance Notes: DOT and MUTCD
The Imperial Estate Series sign face meets MUTCD (Manual on Uniform Traffic Control Devices) design standards for stop sign geometry, color, and lettering. The aluminum substrate and reflective sheeting conform to federal specifications for traffic control devices on roadways open to public travel.
Installing on a public road requires local approval regardless of sign quality. Contact your municipality or transportation department before installation. The rules may be less strict for HOAs and campuses, but using MUTCD guidelines is still the safest and most responsible choice.
Typical approved use cases include municipalities, HOA entrance roads, private community streets, campus intersections, commercial parking lot entrances, and gated developments.
Installation Overview
Here's what a standard Imperial Estate pole installation involves:
Tools and materials: The basic tools include a post hole digger or auger, quick set concrete, a level, a tape measure, and the included mounting hardware.
Dig: Dig to a depth appropriate for your soil type and pole height. A general rule is to bury one-third of the total pole length.
Set post: Place the pole in the hole and plumb it with a level on two perpendicular faces.
Pour and cure: Pour quick-set concrete around the base. Allow full cure time before proceeding. Rushing this step compromises long-term plumb.
Mount sign: Attach the sign face and blade assembly using the provided hardware. Confirm all fasteners are tight before leaving the site.
On sloped ground, measure your above-grade pole height from the high side of the grade. Follow local codes for setback distance from the road edge and use appropriate safety precautions during all ground work.
Why Choose the Imperial Estate Sign?
The Estate Series isn't assembled from mismatched components. Imperial designs the sign face, post, base, and finial as a matched system: same finish batch, same tolerances, same design language. The decorative base and ornamental finial give HOAs and community developments a finished, intentional look at the curb rather than the utilitarian appearance of a standard utility install. You don't spend time hunting compatible hardware or second-guessing whether the post gauge matches the mounting bracket.
The extruded aluminum pole meets ASTM structural standards, which matters for wind load performance in exposed locations. The powder-coated enamel finish is electrostatically applied and oven-cured. It bonds to the metal rather than sitting on top of it. Property managers and HOAs like this system because it keeps the community looking sharp and well cared for over time.
Frequently Asked Questions
What reflectivity do I need for night visibility?
It depends on your traffic environment. Here's a quick guide:
Parking lots and low-speed private drives: Type I Engineering Grade is sufficient
Residential streets and HOA roads: Type III High Intensity is the right baseline
Hazardous or high-speed intersections: Type IV Diamond Grade delivers the highest nighttime visibility
Is this approved for public road use?
The sign face meets MUTCD design standards. Installation on a public road still requires approval from your local transportation authority or municipality. For private roads, HOAs, campuses, and parking areas, no public-road approval is needed, but using MUTCD-compliant signs is recommended for driver recognition and liability protection.
Does the package include custom street name text?
Street name blades come included with the system setup. Custom text is specified at the time of order. Confirm your street name, lettering size, and reflectivity grade when building your sign combo in step two of the configuration process.
What STOP sign size should I choose for a street vs. a private road?
Sign size should match your road type and speed environment. Here's how to decide:
18-inch: Suited for low-speed parking areas and pedestrian-priority zones
24-inch: Standard for residential streets and HOA roads, the most common choice
30-inch: Required on higher-speed roads and recommended wherever MUTCD compliance with arterial standards is needed
