Are you looking for a unique, durable mailbox that will make you the envy of the neighborhood? We have the perfect solution for you! The Charleston Duplex Mailbox and Post Combo System is manufactured by a family owned business in Atlanta, Georgia. We designed the mailbox system to give homeowners a beautiful, long-lasting mailbox. It will bring compliments from your neighbors at a great price point.

The black, powder coated Charleston Duplex Mailbox and Post System is constructed from rust free aluminum. It will stand as a great introduction to your home for years to come. All the necessary hardware is included for assembly and holes are pre-drilled in the mailbox for mounting the number plate. The decorative bracket is an attractive feature that adds stability.

The Mounting Plate is superior to other systems that use wood. The Pineapple Finial is designed to slide into the post for a clean appearance. The address number plate shown in the picture can accommodate up to five 2″ Williamsburg brass numbers which are included in the purchase.

It is designed for easy assembly. The components are pre-drilled. A Phillips head screwdriver, an allen key, and a 7/16” socket or adjustable wrench are required for assembly. Approximate assembly time is 15-20 minutes. Recent improvements have made putting this system together much easier.

This system features a single post that is placed into a hole and secured with a bag of concrete. The actual post is six feet in length and 18” to 28” of the post should be below ground. The actual installation depth depends on the landscaping (raised curb, hillside, etc.) and your height preferences. Our bolt together construction means that replacement parts are readily available in the event that your mailbox is damaged.
