About Cluster Box Units

Our cluster mailboxes are built to USPS standards and are approved by the United States Postal Service. Our CBU's mailboxes are built in the United States and are made to the highest security standards. These Cluster Box Units have been installed in neighborhoods and for commercial mailbox purposes for decades and with recent USPS regulations it appears that they will only become more relevant. Cluster box units as they are some times referred were the primary commercial box on the market just a few years ago, however today there are new styles that are available that offer flexibility away from the 8, 12, 13 & 16 door cluster box sizes.

Frequently Asked Questions
Question: does this include the pedestal?
Answer: Yes, all of the Cluster Boxes on do include a Pedestal.

Question: What is the difference from free standard shipping and curbside shipping?
Answer: For cluster mailboxes we currently offer two upgraded shipping options, they are as follows: Curbside Delivery with Liftgate for $149 and Liftgate and Inside Delivery for $249. Alternatively you can opt for the Standard Free Shipping which does not include a liftgate nor inside delivery.

Question: Whats the difference between your WL-CBU-12-SDBM and the WL-1570-12SAFBM? They look identical on the brochure and are priced the same. It looks like the first one comes with a base and weighs 190 lbs, the second one weighs less at 144 lbs so it must not have a base? Is that correct?
Answer: They are different manufacturers. They both come with a pedestal.

Question: Are there mounting holes in the base on the bottom plate?

Yes, click the link to view the Technical Drawing and in the bottom left you will find the Pedestal Base Bolt Pattern. Thank you.
