13 Door Bronze Postal Products Unlimited F-Spec Cluster Mailbox with Pedestal - Type 4 CBU

Warm Bronze 13-Door USPS Type 4 CBU — Built for Traditional Architecture

The Postal Products Unlimited 13-Door F-Spec Cluster Mailbox in Bronze serves thirteen tenants from a single pedestal-mounted, USPS-approved unit, finished in warm metallic bronze that complements brick, wood, and traditional construction. A parcel locker handles in-place package delivery, and the integrated outgoing mail slot eliminates the need for a separate outgoing receptacle.

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.
