The Reliant post mount mailbox is both a reliable and attractive choice to keep your mail secure. Engineered with heavy-duty galvanized steel, the mailbox features a concealed cam lock compartment to protect your mail. Postal carriers are able to make deliveries through the mail slot opening, which drops into the locked compartment below. The Reliant includes two keys for easy access to you and your household. For outgoing mail, letters can be fastened inside the door with the included mail clip. In addition to its security benefits, steel piano hinges and a sturdy magnetic latch keep the door functioning properly. Pre-drilled bottom mounting holes make installation a breeze. Mounting board and hardware are sold separately.

I bought this to replace my mother’s mailbox. This mailbox is very well crafted and very sturdy. It is also well padded and packaged, so it arrived in perfect condition. It is bigger than a standard residential mailbox, but only by 1-2” on every dimension, so it is not overwhelmingly big. This mailbox is also sold in several different box stores, but Amazon had the best price.

I was so pleased with the quality and look of the box. Easy installation, sturdy construction. Quick delivery. No complaints. I would buy again but probably won't need to because it's built to last a long time.

I did need to purchase the mounting plate which fits on my 4"x4" post. Assembly and installation was very easy. Love the look and enjoying the new locking mailbox.

I am impressed. A heavyweight box that may deter most mail thieves. After owning it a few months I have nothing bad to say.
