For the location and type of soil I have, this product was perfect for my replacement mailbox. The ground screw bit, held, and went all the way into the ground, but per multiple reviews, I think the type of soil you're dealing with makes all the difference between success or failure. This would not be a good choice for sandy soil or dirt loaded with rocks, neither of which I have. Installation took a bit of muscle but the rebar worked. The biggest challenge was getting the ground screw to be perfectly upright. Mine had a little lean to it but we shimmed one side of the 4x4 in the bracket before installing the lag bolts and that corrected any lean the post would have had. I'm happy with the result especially since no hole and no cement were required. Time will tell if this gets wobbly but for now it's solid.

One of the worst things to do is digging holes lol ughđ This thing worked so nice! #thrilled. I had to really grunt and put all my umphf into it to get the last bit down flush with the ground because I didnât want it sticking up and any metal showing like some review pics⌠But I was able to do it and it went pretty well even with only with 2 gallons of water poured in place. I couldâve/shouldâve done more but I was kind of a trek away from my water source and I was in a hurry with minimal motivation/effort in mind lol. Details... Level, drill, drill bit, small tip writing utensil, tape measure, socket/attachments... So first, when I took this thing out of the box I was shocked at how chunky it isđł Beyond reading hundreds of reviews and narrowing down the selection.... I had made a mindful effort to find the longest/cheapest/seemingly best quality one I could (on AMZ). There are so manyđŠ I chose this one because it was slightly longer than my next fave, *the saddle was closest in dimension* for a â4x4â dimensional lumber post (3.5x3.5 actual)- this was important as I wanted it snug & not having a big gap in the saddle for looseness(?)đ¤plus having it be able to stand in its own until I could get a fastener in it was ideal for me đ
, hopefully itâs obvious to seek out a rust resistant finish (fully galvanized is the beat youâll do in this price range) and this one looked pretty goodđ¤ˇđźâď¸ For w/e thatâs worth. Finally, but also very important- I preferred the âamount ofâ and placement of THESE screw holes; over the others I compared.đ¤ Don't bother with a bracket that only allows 2-4 screws in it, and think logically about their placementđđź. and then it seemed kind of stubby when I opened it up & I thought I would be disappointed in my purchase, I was concerned with it not going deep enough to get a really solid bite & be sturdy enough. That was definitely NOT an issue đ. -So the inside of the cone is hollow (as it should be)đ¤ˇđźâď¸ But I didnât expect that, and maybe youâd like to know. -Definitely slowly dump water on the spot where youâre going to do it. Iâd say at least soak a 10 inch area and do it slowly- make sure the water isnât just hitting the surface and then running off the surface somewhere else. Go real slow; letting it absorb. I did 1 gallon and then I used the rod iron that comes with the anchor to hammer into the ground with a small sledge. Wiggle the rod iron around down in there to make your pilot hole bigger/more forgiving. As others said- Be mindful that you make a street and treat that way your post anchor go straight in your post ends up straight. I pulled it back out fairly easily after tht and dumped my other gallon of water in the hole where the where the rod went. Using more water is probably smart, though I wouldnât make a mud hole. -Keep pressure as youâre turning it to keep it straight up and down from all sides. It goes fairly quickly and easily until you get down to the bottom where the anchor is bigger around in diameter and itâs taking more force to get into the ground. I was trying to avoid using my little sledge to get it the last bit so that wouldâve worked well I didnât want to shock and disturb the ground too much and make it potentially less solid/tight- So I just struggled through (a few minutes) and really got into it; I kneeled on the [wet] ground & used my foot to push it away, then pull it around with both hands. -Donât screw it in too far. You want to keep the big holes that you put the rebar through to screw it IN; keep those just above ground level so water doesnât just fill it & sit, AND so if you have to take it out of the ground you can still get to that hole to back it out. -Time for post! âşď¸Youâre almost there! I used and recommend 2 composite shims (hardware store) bring something to snap them off because breaking them by hand like you normally would to install a door isnât going to work as well; they canât be sticking out AT ALL passed your wood post or your post cover may not fitđ¤ˇđźâď¸ at least thatâs how mine wasđ[Mayne post: see photo] no room to spare with its round entry hole. âSquare Peg Round Holeâ. The screws included have kind of a tall hex head on them and they almost stuck out too far for my Mayne post cover, but luckily IT WORKS!đ
and itâs tight- which is good. *shims...I determined which way my post needed to slightly lean since I wasnât absolutely straight with my anchor, and thatâs where I stuck my shim to hold the post straight/snug while I MARKED ALL THE HOLES. Ex: Mark all your holes WITH your shims in place so your post it straight/level. Now take it out carefully & find the very middle of that hole you marked. Drill your pilot hole put the post back with the shims in place again (I would break them off to the right size at this time then stick them back in there) and screw that ONE screw in your ONE pilot hole. (you can screw through your shim) check your levels & adjust your shims where you need. Now do the opposite sideâs hole (which direction does the post need to pull) and check your levels once more. Now drill all the rest of them and screw the rest in while checking straightness. You have to figure out where to screw it first so that you can get that post to pull which ever direction you need it to Remove the post/shims and drill 1 or 2 hole/s for your screw (I only did one at first in the front (where my post needed pulled), and checked it/adjust shims, then do the opposite side (where your other shim likely is) and if everything looks good- drill that hole & screw it so u have 1 in front & 1 back. If itâs straight and level check your marks find the center & drill/screw the rest. -Obviously when screwing in your anchor make sure itâs square with the road or however youâre going to be facing your post. You donât want to back it out if itâs not straight where you want it I would just screw it in one more turn. Since I was doing a mailbox I chose to have the saddle plates facing the street since thatâs the direction itâs going to be pulled on the most and I need it to be most secure their. Iâm falling asleep đ hopefully that was somewhat in order & coherent đ¤Śđźâď¸ I will likely edit another day đ Good luck!!! A definite buy! Huge time saver

The American Ground Screw U-Model Ground Anchor has proven to be a robust and reliable solution for securing my mailbox. Living in an area prone to heavy snowstorms, I've often faced the frustration of my mailbox succumbing to the force of snow plows. However, since installing this ground anchor, my mailbox has withstood two significant snowstorms, a feat it never achieved before. Upon receiving the unit, I noticed it lacked the necessary screws for installation. However, the seller was highly responsive and efficient in resolving this issue. After a quick message, the missing screws were promptly dispatched, demonstrating excellent customer service. A word of caution to potential users: the unit is quite sharp and has jagged edges, so handle it with care before installation. Installing the ground anchor is straightforward but requires considerable effort. I had to split the installation process into two sessions due to its physical demands. The design is practical, with the original mailbox post fitting snugly between the two metal pieces that protrude upwards. The pre-drilled holes for the screws are a thoughtful addition, although it's necessary to have someone hold the mailbox in place while you secure it. This minor inconvenience is worth the stability and durability it offers. Overall, I am extremely satisfied with the American Ground Screw U-Model Ground Anchor. It provides a sturdy, no-dig solution for outdoor installations. Despite the initial hiccup with the missing screws and the physical effort required for installation, the end result is a secure and durable anchor that has already proven its worth in challenging weather conditions. I highly recommend it to anyone seeking a reliable ground anchoring solution.

I had high hopes for this product, but wasn't able to screw it into the ground. I tried three different locations only to hit rocks well short screw's length. Rocks stop the screw. I used a 2ft drill bit and cordless drill look for a spot without rocks, but I couldn't find one. I ended up using a pick and a post hole digger to dig a hole for the screw, which is just what I was hoping to avoid in the first place. Nevertheless I'm giving it 3 stars because I didn't have to use concrete and I can remove it if I need to, and because I think it should work well with the right type of soil. My advice for someone who wants to use this is to try the drill test and make sure there are no rocks where you want to put it. If not then you may have to dig a hole.

But it takes a 2x4x8 to screw out all the way down and I started with a hole about 12â deep. The included handle works for the first few inches. But once itâs in itâs very stable. I used it for my mailbox post that had rotted off at ground level. Think itâll work out well
