## Description

Meet the Oasis 360 post mounted mailbox, a true front-yard upgrade with brains, brawn, and curb appeal. This metal mailbox combines sleek design with serious security, making it a standout in our USPS approved locking mailboxes collection. The double door mailbox setup lets you grab your mail from the back, so you can skip the street and the traffic. A magnetic latch keeps the door sealed tight, and the built-in WeatherTite™ strip keeps your mail dry, even when the forecast goes sideways. With its spacious large mailbox compartment, there’s room for magazines, padded mailers, and all those impulse buys. You’ll even get four keys for family mail check duty. No need to distribute keys to your mail carrier, they deliver through the top door, securely depositing your mail in the locked compartment below. Whether you’re upgrading residential mailboxes, refreshing your curbside mailbox, or need an outdoor mailbox that can handle your mail with style, the Oasis 360 has you covered. It’s tough, trustworthy, and totally made for mailboxes for outside that do more than just sit pretty.

Review: Elegance through simple design, sturdy build quality, secure mail. - I highly recommend the Oasis 3600 locking mailbox. Highs: Pleasing, simple look. Sturdy, weather-resistant build quality. Joints/seams are weather-sealed. Magnetic latch ensures door stays shut even in windy weather. Hopper-type door ensures mail and small packages and all your mail yet prevents theft. Both front and rear access to mail retrieval. Manufacturer provides four (4) keys! Lows: If mounting to a post, the post and the mounting hardware are sold separately. Not the friendliest design for outgoing mail. We wanted a curved design to ensure that gravity takes the rain off the mailbox—it does! I chose the satin black finish. This is a powdercoated finish. I’ve heard of people applying car wax to further protect the finish. I live in a rainy area and so that might be something that I’ll do regularly. Mounting was easy and is done from the inside. There are four (4) 3/8 inch holes spaced 4 inches and 10 inches apart. Since my mailbox sits atop a platform custom build atop a chain link fence rail, I used a 1 inch thick plywood base, and secured the mailbox using 5/16 inch diameter lag screws fitted with flat washers. I chose larger screws because this mailbox is heavy—about 14 Lbs. I chose black color because it will be easy to touch any dings that will inevitably happen in the coming years. I have some recent history with this very mailbox because I installed this exact unit at my business property a year ago. It has performed so well, and since we had recent mail theft at home, that it was time for an upgrade. I expect this mailbox to last decades.
Review: Very good quality, well made and elegant mail box. - A very durable, very good quality mailbox. It holds a large amount of mail, well made and looks very good. I am very pleased with the purchase. It is not too heavy. I purchased a sturdy post to go with it.

### ⭐⭐⭐⭐⭐ Solid, Secure, Built to Last!
*by E***A on November 12, 2025*

I’m extremely pleased with the Architectural Mailboxes Oasis 360. The build quality is outstanding — heavy-duty metal construction that feels solid the moment you unbox it. It has a nice weight to it, which adds to the sense of durability and stability once installed. The security is top-notch. The lockability feature works smoothly, and the locking mechanism feels sturdy, not flimsy like cheaper models. I can finally say this mailbox really keeps thieves away — I’ve had no issues with mail tampering since upgrading to this model. It’s also USPS approved, which gave me peace of mind that it meets postal standards. After several months outside, I’ve noticed no signs of rust, even through rain and humidity. The finish still looks brand new. Overall, it’s a well-engineered, rust-resistant, and highly secure mailbox that’s worth every penny. Perfect if you want both protection and style in one package.
