Sterling Onyx

Product Overview

Bring together timeless design, added mail security, and superior weather resistance with the Sterling Aluminum Onyx Mailbox.

The Sterling is constructed around a durable 4" × 4" powder-coated aluminum post, creating the traditional appearance of a classic post-mounted mailbox without the maintenance concerns commonly associated with wood or steel posts. Its clean profile works beautifully with modern, contemporary, transitional, and traditional architecture.

This upgraded version includes the locking Onyx mailbox constructed from aluminum. The aluminum mailbox and post provide excellent resistance to rust, moisture, humidity, and coastal conditions, making this combination especially well suited for South Florida homes and other demanding outdoor environments.

The locking front door helps provide additional protection for incoming mail, while the outgoing-mail flag maintains the everyday convenience of a traditional curbside mailbox. Available in black or white, the Sterling Aluminum Onyx delivers a refined appearance with enhanced durability and security.
