## 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: Second try at finding a good locking mailbox - I like this one. It’s sturdy, wasn’t hard to mount on my existing 4 x4 wooden post (with the steel mounting bracket that you have to buy separately) and it looks nice. The mail stays dry and the slot is big enough that the mailman doesn’t have to crumple up the mail to get it inside. It’s kind of big, but I like that it’s mailbox-shaped so it doesn’t call too much attention to itself. It remains to be seen how it holds up to thievery, but the locks seem to be pretty heavy duty. If you’re getting your mail stolen, give this one a try.
Review: Good quality - This is a well constructed box. It is along a busy No. CA road and so far I've had no problems. It is strong & waterproof and locks securely. I mounted it on a steel post in cement so it's not going anywhere.

This is a well constructed box. It is along a busy No. CA road and so far I've had no problems. It is strong & waterproof and locks securely. I mounted it on a steel post in cement so it's not going anywhere.

### ⭐⭐⭐⭐⭐ Sturdy construction!
*by C***E on September 25, 2025*

I waited to use this for a month and I am impressed! Very well made, good key lock. The only setback would be the mail carrier can't put a medium PKG in the slot. It will take a medication bottle size. Worth the money for sure.
