13 Door CBU Mailbox - Sandstone

If youíre putting together a new housing development, then youíve probably already considered a multi-unit cluster mailbox or have worked with your architect to lay out the location of each individual cluster mailbox. The 13-Door Cluster Box Unit is a central mail hub thatís easy for both residents and postal workers to access. And, as you can guess from the name, it will provide mail access for up to 13 tenants (or in multiples of 13 tenants if you purchase more than one unit).

For residents, the CBU provides a secure place to retrieve and leave their mail for pick-up. For the postal workers, it cuts down on time and makes them more efficient with deliveries. There is also one (1) large parcel unit to hold larger packages. The mailbox is built to USPS specifications and is pre-approved for outdoor, central mail delivery. Further, it is a relatively quick installation if your concrete pad is already prepared according to USPS specifications. If you need more information about installing the CBU, please watch the Installation Tutorial Video by Auth Florence (hint: itís the video on the right).

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 provided it meets USPS height specifications.

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.

Frequently Asked Questions
Question: How exactly does the US post office get access to place our mail in our boxes and access the outgoing mail as well? Do I have to give them a master key or are the locks built-compliant in a way that USPS already has a key?
Answer:Actually the post office will need to come out and install master locks in the outgoing mail compartment and the parcel boxes. The lock they install allows them to open the unit like two large double doors, giving them complete access to each individual box.
