12 Door Black Postal Products Unlimited F-Spec Cluster Mailbox with Pedestal - Type 2 CBU

Twelve-Tenant USPS F-Spec CBU in Matte Black — Modern, Secure, Compliant

The Postal Products Unlimited 12-Door F-Spec Cluster Mailbox in Black is a USPS Type 2 cluster mailbox that combines clean modern aesthetics with hardened security. The matte black powder coat is the most-specified finish on new multi-family construction — it reads as architectural rather than utilitarian, and it pairs cleanly with black window frames, dark fascias, and contemporary signage. Twelve tenant compartments, one parcel locker, and an outgoing mail slot serve a mid-size building from a single weatherproof pedestal-mounted unit.

About the Manufacturer — Postal Products Unlimited

Postal Products Unlimited (PPU) is a USPS-approved manufacturer of commercial cluster mailboxes with a 25+ year history and ISO 9001:2015 certified quality management. PPU's F-Spec CBUs share the USPS specification with Auth-Florence's 1570-series and Salsbury Industries' 33-series cluster mailboxes — same dimensions, same door counts, same security features, same USPS approval — and give you a third brand option when matching an existing on-property mailbox or sourcing a backup supplier. We carry the full line in all four powder-coat finishes.
