If you live in the United States, you are generally not liable if someone hits your mailbox with their car. This is because, under the law, mailboxes are considered "fixtures" attached to the property, and are therefore the responsibility of the property owner, not the driver. There are some exceptions to this rule, however. For example, if the mailbox was not properly installed or maintained, or if it was placed in an unsafe location, the property owner may be held liable.
Yes, you can use quikrete for a mailbox post. It is a good idea to use a level when you are pouring the quikrete so that your mailbox post will be level when it dries.
You can concrete a mailbox post in the ground, but it is not recommended. Concreting a mailbox post in the ground can make it difficult to remove the post if you need to replace it or move it.
You can pour dry concrete in a post hole, but you need to be sure that the post hole is dry as well. If the post hole is wet, the concrete will not set properly and will not be as strong as it should be.

To support the Mail Boss 7106 mail box, I bought the 7121 post. The hollow inside of the 4"x4" Mail Boss 7121 in-ground steel post allows it to fit snuggly over a typical 3.5"x3.5" wood post (although the wood post will need to be reasonably straight). The steel post is 14 pounds in weight. It has a square, 4 and 3/8 inch wide steel top plate that is securely welded over the top end of the post and is totally open at the bottom. The post's steel walls are around 1/16" thick and very strong. The top plate has four threaded holes that are 3 and 11/32 inches (center-to-center) apart and arranged in a square. The four holes penetrate the top plate and enter the post's hollow interior (not outside of it). Four of the 24 3/8" holes on the mounting plate that comes with the Mail Boss 7106 mail box perfectly line up with the four threaded holes on the top plate of the 7121 steel post. The mounting plate has 24 3/8" holes total that are symmetrically arranged in it. The mounting plate can be fastened to the steel post using the four lag bolts that are included with the post. Strangely, a 12 inch wrench will shear the drive head of these four lag bolts, necessitating the use of an 11 mm tool. It's really odd that they would utilize 11 mm heads rather than 12 inch. One of the post's four sides is undrilled, but the other three each have two 5/16" holes that are spaced 1 and 3/8 inch (to the hole's center) and 4 and 3/8 inch apart from the bottom of the post, respectively. Six No. 10 (or 14 inch by 2 inch) lag screws or the like can be used in these holes to fasten the steel post to a 3.5"x3.5" wood post; these screws are not included and must be purchased separately. In order to prevent potential corrosion caused by different metals where the screw head contacts the galvanized steel post after it is buried in the ground, I would only use a zinc-coated steel lag screw (19 cents per piece at any Home Depot).The 7121 post was completely black, as was the 7106 postal box. The mounting plate is fastened to the post's top plate after it has been driven into the ground. Once the mail box is mounted on the mounting plate and fastened to it with the two bolts mentioned above, which can only be accessed by opening the mail door with one of the provided keys, the heads of these bolts will be inaccessible to a thief. One fastens the mounting plate to the post with two bolts before sliding the mail box onto the mounting plate and fastening it in place. A burglar cannot access any bolt or screw until they unlock the locking door.According to US postal standards, the mail box's entry slot must be between 41 and 45 inches above the ground. When the mail box is fixed on the post using the provided mounting plate, the mail entry slot on this mail box is about 12 inches above the top plate of the steel post. Given that the post is 43", you can only embed 10 to 14 inches of the steel post into the ground if the roadway is level with the surface where the postal box will be mounted. You might be able to sink the steel post a little deeper if you are on a residential street with a curb and you want to put the mail box into ground that is a few inches above the street level. Even if you concrete the post all the way up to the surface, it still probably won't be deep enough to hold the heavy mail box securely. If you don't use concrete, it's very probable that you'll want to use a pressure-treated wood post inside the hollow steel post to enable you to sink the post much deeper. You should ideally be at least 3 to 4 feet below the surface in frigid conditions. Keep in mind that the postal box's front face should be between 6 and 8 inches away from the side of the road (close enough for the postman to reach it comfortably but not so close that he hits the mirror of his van on it).My 7121 steel post was installed by a handyman (with a longer wood post inside it). The concrete footing from the prior mailbox post was tough to disassemble and remove, so even though he requested $150, I paid him a bit extra. To install my post, he needed an 80-pound bag of Quikrete. Once everything was set up, mounting the mailbox onto the post was simple and quick.

First off, the mailbox post is not included with this kit (the part that goes into the hole surrounded by concrete). This is a plastic cover made to go over a 4x4 stud that you will be responsible for providing. That required me to make a second trip to the hardware store.In order to provide free copies of the Muller Report to our neighbors, we set up our MuellerBox on this mailbox post. Unfortunately, some of the President's more outrageous supporters are violent, as evidenced by the damage that was done to the attached mailbox by what appears to be a fist. You screw a mailbox base adapter into this corrugated plastic mailbox post (adapter onto post, mailbox onto adapter). The impact tore many of those screws out of the plastic.But I had no trouble fixing the mailbox. I had to take the mailbox out completely. The holes in the corrugated plastic are about an inch wide, so this was fairly simple to do using scrap wood that was already lying around the garage. After this was finished, I secured the mailbox base adapter back onto the post arm. I then used screws to attach the base to the post through the plastic reinforcement and into the wood. Our mailbox is now prepared to respond if it is punched once more.Overall, this device has a great design and is simple to set up and maintain. If you have any yahoos in your own area, take into account some post-arm reinforcement.

Since I am nearing the conclusion of repairs, I decided to replace the mailbox I lost in the Montecito mudslide with this stand and the mailbox that goes with it. When I bought a black stand, I got one that was white, even though a black mailbox was meant to match! I must now paint it. Painting it yourself is never the same, but I can't wait since I've already opened the package, dug the hole, and have a helper waiting for the installation. No matter what, I would have to give him money.I'm really bummed about that. Otherwise excellent.

This must fit over a 4x4 post, which you can purchase from any hardware shop. Nothing major. This post is easy to put together and has a beautiful appearance.The post's low 42-inch height is the only thing I would criticise. The USPS is very clear that the mailbox's floor must be at least 42" and at most 45". Therefore, you must leave some of the bottom of the wood post visible if you wish to meet those regulations. The wood was spray painted black. I'm not sure why the business would fall short of the USPS standard, but it's not really a big deal because nobody will really notice it.

The polish first appeared to be less sturdy than I had hoped and a little glossier. But from a distance after installation, it doesn't appear that horrible. I surrounded it with pebbles in the hopes that my lawn crews wouldn't destroy it.I wanted the post to stand 45" above the ground because it appears that postmen prefer taller heights, and that is the USPS's recommended maximum height. The post isn't tall enough and isn't thick enough, according to our installer, so if I build it that high, it won't be very stable. He also put cement inside the pillar to further stabilize it.I used this with an Architectural Mailboxes Model #: 5591B-10 from Lowe's, which costs half as much as other mailboxes of the same kind sold on Amazon. In my opinion, it is much better because the trim matches the mailbox's color. My postman likes the magnetic mailbox closure since it is so secure. The combo seems far more expensive than what I paid for, according to my neighbors.I saw in a review that this was produced in the USA. Although both of the finishes I ordered were created in China, I don't think it matters for something like a mailbox. Just letting you know about the upgrade

It was delivered on schedule and is incredibly beautiful! made from a sturdy, substantial material! I can't wait to install it. Will provide an update this weekend.The installation was simple-peasy. Installing this mailbox would be simple if you have any DIY experience. Digging the post hole was perhaps the most difficult task for me, but it looks fantastic!Additionally, I'm not sure what other people were complaining about. It isn't fragile and fits snugly over a 4 by 4 post. Who cares if the arm is a little shaky. Unless you spend the entire day on the curb shaking your mailbox arm, you can't tell it's wobbly.

There is no definitive answer to this question as it depends on local building codes. In some areas, mailbox posts are required to be breakaway to protect against damage from vehicles. In other areas, there are no specific requirements regarding mailbox posts.
A mailbox post is a support for a mailbox that is usually made of wood or metal. Most mailbox posts are made of wood. A metal post may be used if the mailbox is going to be subject to a lot of wear and tear. If you are using a wood post, you will need to use gravel to help keep the post in place.
You will need to pour concrete for a mailbox post if you are mounting the mailbox on a wooden post. The concrete will help to keep the mailbox secure and in place. It is important to make sure that the concrete is level so that the mailbox does not tilt to one side.
To stabilize a mailbox post, you will need to use a 4x4 wooden post and concrete. First, dig a hole that is two feet deep and wide enough to fit the wooden post. Next, mix the concrete and pour it into the hole. Once the concrete has set, you can then attach the mailbox to the post.
A wooden mailbox post can last for many years if it is made from a rot-resistant wood, such as cedar, and is properly maintained. The post will need to be replaced sooner if it is made from a less durable wood, such as pine, or if it is not regularly treated with a waterproofing sealant.
4x4 posts for mailboxes should be a minimum of 8 feet tall. This will ensure that the mailbox is high enough for most people to reach, but not so high that it's difficult to retrieve mail from.
