Product Description

The Centennial Post Mount Mailbox and Premium Steel Post Combination is your all-in-1 quick fix to improve your curb appeal and the solution to receive many or large packages. The Centennial Mailbox by Architectural Mailboxes is the first design to receive United States Postal Service approval against the new USPS Standard 7C regulation, released in late 2015. It’s large and ample mailbox compartment is designed to receive not only mail and magazines but multiple parcels. This means no more missed deliveries or parcels left out on the porch exposed to weather and thieves. Made with quality construction and heavy gauge materials complete with a die cast aluminum handle and rigid, powder coated steel flag. The Centennial is mounted onto a premium 3-inch diameter in-ground post constructed of 19-Gauge galvanized steel and fully powder coated for added durability and corrosion resistance. The decorative post has an upper skirt to hide any unsightly mounting hardware for your post mount mailbox. The two-piece decorative post cover wraps around the bottom of the post and is constructed of ABS with UV inhibitors to resist fading and discoloration. The decorative post cover hides unattractive concrete work while providing an elegant, finished look. This attractive design combines aesthetics and functionality servicing all your mail and parcel needs in one kit.
