Centennial Postmount Mailbox XL Black

Architectural Mailboxes presents the Centennial Mailbox, the inaugural design to receive approval from the United States Postal Service under the new USPS Standard 7C regulation, which was issued in late 2015. Named the Centennial, this revolutionary mailbox represents the next generation in mailbox sizing, marking the first change since the traditional size was established over a century ago in 1915.

With an ample compartment, the Centennial mailbox is crafted to meet the needs of today's consumers by accommodating not only mail and magazines, but also multiple parcels. This means no more missed deliveries or parcels left exposed to harsh weather and potential theft.

Constructed with high-quality materials and heavy gauge construction, it features a die cast aluminum handle and a rigid, powder coated steel flag. This elegant design seamlessly merges aesthetics with functionality to fulfill all your mail and parcel needs. The spacious inner compartment can even accommodate a USPS priority mail large flat rate box measuring 12 inches by 12 inches by 5.5 inches, while still leaving room for additional mail and parcels.

The heavy gauge galvanized steel body is equipped with stainless steel door pins and fully powder coated to resist corrosion. The sleek magnetic door closure ensures reliability while keeping the door securely closed. Additionally, the predrilled 4 inch by 10 inch hole pattern in the floor allows for easy mounting to an existing post (installation hardware not included). For installation on a 4x4 wood post, the Architectural Mailboxes adapter plate 7540B is required.

Overall dimensions for the Centennial Mailbox are 14 inches in width, 12 inches in height, and 18.3 inches in depth. Approved by the US postmaster general, this piece works seamlessly with Architectural Mailboxes post models 5526, 5525, 7516, and 7507.
