12 Door CBU Mailbox - Sandstone

Weblife Cluster Box Units - Front Loading

The 12 Door Cluster Mailbox includes 12 standard sized (MB1) tenant doors, each secured with a stainless steel cam lock, and one 1 (PL5) parcel locker for package deliveries. If you need additional parcel lockers for your cluster mailbox, you can purchase stand-alone units here. This smart, cost-effective solution makes a great addition to any new housing or commercial development.

This unit is USPS approved and meets all postal service specifications for outdoor mail delivery for new developments: it is pre-approved for residential communities and commercial complexes (please note that while the CBU is USPS approved, it must also be installed according to USPS specifications). If you have questions about installing a mailbox, feel free to reach out to us or take a closer look at our installation instructions (opens as a downloadable PDF file). With standard numbering, the individual tenants are marked 1 through 12 and a unique key is assigned to each tenant.

Made of heavy duty aluminum and stainless steel hardware, Weblife 3300 series USPS approved pedestal Cluster Box Units (CBUs) are accessed from the front through two (2) easy opening master door panels. The durable and corrosion resistant units feature a powder coated finish available in six (6) contemporary colors and can be mounted on the included pedestals (#3385 for #3316 or #3313 and #3395 for #3308 or #3312) or a base of your choice as long as it meets USPS height requirements. Each aluminum door includes a heavy duty five (5) cylinder cam lock with a dust/rain shield and three (3) keys. One additional compartment in each unit is labeled “Outgoing Mail" and includes a weather protection flap and an 11-3/4" W x 3/4" H mail slot. Each unit includes one or two (2) fully integrated parcel lockers. An attractive option to CBUs for new and existing CBU installations are Weblife 3300R series USPS approved Regency Decorative CBUs.

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: What's 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. 

Question: I would like to ask if the pedestal is included with this mailbox
