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.

Choose Your Finish

• Grey — neutral, the most versatile across brick, beige, and stucco
• Bronze — warm metallic; pairs with brick, wood, and traditional architecture
• Black — modern matte; the most-specified finish on new multi-family construction
• Sandstone — soft beige; ideal for stucco, adobe, and warm color palettes
