    This is a mailbox, not a post. The Brighton aluminum post is sturdy in the ground when used with concrete and is NOT meant to be used with a 4 x 4 wooden post. Use concrete with the post. Use this mailbox for a 100% aluminum mailbox installation.

            Is this mailbox made from aluminum or steel? The first bullet point says "heavy gauge steel construction" and the third bullet point says "60% thicker aluminum construction". So, the description says is made from steel and/or aluminum, is it both?

              How well will this mailbox with stand the snowplow? We people who live in the cold rural regions really need the option for a mailbox that will hold up to a direct hit from the snow plow
              ByApr 24, 2023
              1 Answer | 
              Answer This Question

              No mailbox would stand up to a snow plow crash, just like none of them stand up to a car crash. Move the mailbox further from the street or have a health problem. Then you can install a wall-mount mailbox.

                Good aluminum mailbox, medium size, 6.9 x 9.5 x 20.8 inches. Has a nice double lip on the door that should keep most rain out. It feels lighter than I was expecting, but aluminum is like that. Got this to replace my steel mailbox that was rusting out - after replacing another rusty mailbox about 10 years ago. I hope the aluminum one holds up better. The white paint has a textured surface, it is not shiny. Even the flag seems to be made out of aluminum. My one complaint is that the inside is not really finished - only some overspray from the door. I think I will spray the inside with some white spray paint to help protect it a little better.

                i was in need of a new mailbox as the before photo shows. Having retired from the U S Postal Service, I had good knowledge of a serviceable box. With wind and rain a problem keeping the mail dry, this box provides an interior lip that facilitates dry mail, even if the box isn’t securely shut. The box should be serviceable for years to come and I don’t believe a person could go wrong with this purchase.

                The Admiral model mailbox from Gibraltar Mailbox Co. is definitely not a "standard old" mailbox. It is built of quality aluminum construction (rust-proof), very nicely finished with a powder-coat, textured black finish and is expertly constructed with nice looking seams & corners. This mailbox is a bit larger than a standard sized mailbox (manufacturer indicates MEDIUM size), but is not as large a as my mailbox it is replacing. This one is approx.21" X 7" X 9.5". My current box is approx 21" X 8" X 11" , but I will try this one to see how it works (will probably be a bit tight for larger envelopes and small boxes.) It mounted easily onto the current base of my mailbox post. So, if you're looking for a nicer looking "standout" mailbox to put in front of your house, this one would be a good choice!

                An ideal "regular" sized (smaller) mailbox. Wholly adequate for general letters, a few newspapers, magazines and circulars. But, if you receive more mail parcels than an occasional one- or two-pound USPS flat rate box, consider getting a larger "rural" sized mailbox. See photograph 1. Comes with the flag assembled. It has a good detent to keep it upright. The box is quite weathertight due to the double lip door edge (shaped like a rain gutter) which engages the shell. See photograph 2. This seems to keep the box from blowing open. it also rigidifies the door and maintains its alignment without stressing the hinge pin (a common weakness in others). The mailbox bottom is outlined with numerous convenient mounting holes. See photograph 3. These permit secure fastening to a fitted timber post cap, making installation easy for a DIY woodworker. The best feature of this mailbox is its longevity. The aluminum construction deters corrosion and the matte powder coat finish looks attractive.

                What can be said about a mailbox? This one is nicely built, has a very nice finish, and a good feel to the door and flag. I wouldn't consider this a "large" mailbox, as it seems to be the same size as the standard mailboxes I was looking at. It was a good thing I replaced my original mailbox when I did, as the wood baseplate has started falling apart, and would have failed during the next heavy door-slam! The one thing I could ask for in a mailbox was missing... and that's a base which allows a standard width of lumber to be used without having to rip it. I did end up using a piece of 6-inch wide pressure-treat for the base, but had to shim the attachment points. Easy enough to make work. Highly recommended mailbox!!

                This is a replacement for an old rusty mailbox. One of the reasons that I chose this mailbox is that it is powder coated aluminum. Between the powder coating and being aluminum it should look good for years. I noticed when I took it out of the box that it was completely assembled. A lot of the mailboxes require that you attach the door and flag. Another reason for the replacement is that the old box was missing the little pull strap on the door. While it was possible to get the door open it was a bit hard on the fingernails! This box has a very robust pull tab on the door that will make opening it a lot easier especially in snowy and icy weather.

                If you're tired of sanding and painting your old rusting steel mailbox (I was), this might be the mailbox for you. It features rustproof construction to prevent rust and salt corrosion. It also has a cleverly-designed door to keep rain out of the mailbox. This mailbox is labeled as medium sized, which looks like the standard size of rural mailboxes. Keep in mind that the mounting bracket is not included with the mailbox (those usually come with the mailbox post when you purchase that separately). A nice, weather-resistant mailbox that should last a good long time.

                This is a well made aluminum mailbox that should keep your mail dry and safe from the elements. It comes fully assembled with the flag already installed. Being aluminum, it will not rust and will be resistant to the weather. It is covered in a good coating of black textured paint. The dimensions of the mailbox are clearly marked on the box including samples of the type mail that will fit in the box.
