Salsbury 3300 Series Cluster Box Units (CBU's) - USPS Access

Cluster Box Units (CBU’s) manufactured by Salsbury Industries provide USPS access and offer a secure means of receiving mail and packages. They are ideal for commercial use or residential applications such as housing developments, apartments or townhouses. The 3300 Series is a USPS accessible CBU that includes a matching pedestal. Our cluster mailboxes are an excellent choice for durability because they are constructed of heavy-duty aluminum and stainless steel. Note: For Private Access applications such as colleges and military bases where a non-USPS employee will be delivering mail, order Master Commercial Locks (P/N 3375) for the access door and individual parcel locker(s).  See the additional features of our CBU’s below.
