About Product Overview

The Oasis mailbox from Architectural Mailboxes brings a locking, secure design to a modern post-mount box, built from galvanized steel with a black powder-coated finish that resists rust and stands up to impact. Mail goes in through a hopper opening on the front, so carriers drop letters and packages in without needing a key, while an outgoing mail indicator flags pickups for your carrier. Rear access lets you retrieve mail from the back without exposing the lock side, and the lock keeps everything secure between pickups. No assembly is required, which means it's ready to mount and use right out of the box. This Oasis 360 sub-brand mailbox carries US Postmaster General approval, so it meets the size and access requirements the postal service requires for curbside delivery. Its clean, modern lines and black finish make it a good fit for homeowners who want a mailbox that looks current and holds up outdoors year after year, without fading or rusting.

  • Lockable with rear access for secure mail retrieval

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
