8 Door CBU Mailbox - Sandstone

Weblife Cluster Box Units - Front Loading

When it comes to finding the perfect centralized mail solution for a new housing development or commercial space, the 8-Door Cluster Mailbox in Sandstone is an excellent and USPS preferred choice. This smart and easy to manage unit provides new residential or commercial developments with a central mailbox location so that mail retrieval and delivery are simplified.

The 8-door cluster mailbox is one of our best sellers and has gained that top spot for a reason—it’s efficient, effective, and relatively easy to install. In the unit, there are 8 mailbox tenants and 2 parcel lockers for larger packages. To keep each individual mailbox safe from intruders and outside elements, the CBU is fitted with heavy-duty cam locks. All outgoing mail is dropped into the mail slot labeled “Outgoing Mail.” It is really that simple.

Created to USPS specifications, the standard 8 Door Cluster Mailbox is pre-approved for outdoor, centralized mail delivery in neighborhoods and commercial spaces. If you are a contractor or developer working on a new construction project, the cluster mailbox is the simplest choice for meeting USPS regulations. If you are looking for a more decorative alternative, you can dress up the 8-door cluster box unit with the optional CBU decorative top and post cover (see our decorative CBU options for more details). Each mail compartment is individually numbered with its own tenant key, and the outgoing mail slot is tamper-proof. So, once your mail is inside the unit, it is there to stay until you or an authorized postal worker takes it out.

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 is designed to be mounted on the included pedestals (#3385 for #3316 or #3313 and #3395 for #3308 or #3312) or a base of your choice (must meet 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.
