8 Door Black Postal Products Unlimited F-Spec Cluster Mailbox with Pedestal - Type 1 CBU

Modern Black-Finish 8-Tenant Cluster Mailbox Built to USPS F-Spec

The Postal Products Unlimited 8-Door F-Spec Cluster Mailbox in Black pairs a clean modern aesthetic with the same USPS-approved security and weather resistance you'd expect from a commercial cluster mailbox. The matte black powder-coat finish is the most popular choice for contemporary multi-family construction, mixed-use developments, and any property where mailbox hardware should disappear into a black-trimmed building palette. Inside the finish: heavy stainless steel and aluminum, USPS-developed locks, and a security envelope rated for decades of outdoor use.

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.
