Simplified Delivery With a 4 Unit Mailbox

If you have four units or a business with four separate offices, a quad mailbox post is the way to go. A 4 unit mailbox means each user has their own dedicated space for their mail and the entire setup fits into one post giving your exterior a cohesive look.

Benefits of a Quad Mailbox Post

  • Convenience
    Four mailboxes in one spot makes daily operations smooth for both residents and mail carriers.

  • Security
    By consolidating mailboxes you can easier monitor for tampering and keep the area well lit if needed.

  • Aesthetics
    One post with four boxes looks better than multiple standalone units scattered across the property.

USPS Compliance and Placement

  • Standard Height: Set the lower box openings around 41–45 inches above ground level.

  • Label Each Unit: Use numbered or lettered plates so carriers and tenants can identify the correct box at a glance.

  • Distance: 6–8 inches from the curb; make sure your quad post doesn’t block traffic or sidewalks.

Installing Your Quad Mailbox Post

  • High Quality Materials: Look for galvanized steel or aluminum posts that can withstand rust and seasonal changes.

  • Sturdy Anchorage: With four mailboxes the post has to handle extra weight. Consider concrete footings or deeper post holes.

  • Community Rules: Always check local regulations on mailbox installations before you start.

Top Brands

  • Whitehall Products: Combines style with solid aluminum construction for weather resistance.

  • Salsbury Industries: Dependable and USPS approved; perfect for residential and commercial use.

  • Mailboss: Robust security with locking features; great if mail theft or vandalism is a concern.
