Please note: This product is currently on backorder from the manufacturer. We estimate it will be available to ship on or after 06/15/2026. If you'd like to purchase today, we will hold your order until the product is ready to ship.
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.
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.
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:
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.
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.
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) 685-7873 . We will provide you with your Order Number and any other details you need.
