Vortex (1-Pack) 16" Spiral Ground Anchors, Steel Screw In with Folding Ring, 425 lb Pull Force, Orange ANCFR16-ORG-A

I love these ground screws!! After years of trying to drive stakes into the ground to hold up various shrubbery as they mature, these screws are the answer. Stakes bend, break, and rope tends to slip after time. These screws are the perfect remedy. They easily drive into the ground, even when that ground is hard clay, and they stay put! The eyeholes on the tops of the screws are well made and are easy to attach to. I also use them to keep various sports goals and nets in place so they don't move with windy days.

I love these! I’m not a pro builder or anything, but you can cleverly use these to strengthen your diy structures, such as the garden I have. All you do is twist it into the ground (all the way until it’s leveled). I used a long screwdriver to help me as it gets deeper. You can easily remove it by twisting back up. The thickness is pretty solid. The appearance is shiny and sleek. It holds and supports a lot of weight under tension and even stays put through rains. You can use it for many builds if you also use ratchet straps as I did. Overall it’s solid and I’ve already bought a second pair.

I needed ground anchors for my Slackline, but have not gotten around to installing a more permanent solution yet. I've looked for anchors that can withstand the tremendous pull forces due to the tension on a slack line, and these looked like the best candidate I could find online. Some tension calculators estimate over1000lbs of tension on the line. The anchor is rated at 425lbs pull in an upward direction, as indicated by an arrow pointing away from the ground on the diagram on the product tag. (See attached photo) I used two anchors on each end of the slackline (total of 4 anchors) with the slackline pulling on each anchor at 30 degrees from horizontal. Two anchors on each side of the line are further spaced 4 feet apart with 4 feet of tow chain to the slackline. This helps to further distribute the tension on the anchors. Each 16" anchor is screwed flush into my lawn which is around 6 inches of soil/dirt with clay/rocks/gravel underneath. The slackline is about 2 feet off the ground, so if an anchor fails, I won't fall too far. Also, by using two anchors on each end, if one were to fail, the other anchor should help prevent the end of the tensioned line from shooting toward the user on the line. I'm not using this line for bouncing or jumping tricks. I'm only using it to learn to balance and walk the line. So far, so good. Everything seems pretty solid and the anchors are holding tight. I leave the anchors in the ground 24/7. I used a crowbar to screw them in. When using the slackline, the top of the anchors appear to deflect by about 1/2 inch or so, but they don't look like they will pull out of the ground, especially since the pulling force is closer to horizontal. I would rather use large trees as anchors, but since I don't have any in my yard, this serves as a pretty handy substitute! This application is probably stressing the product more than average, so use at your own risk!

Used this as an anchor point for a guy wire for a patio lighting pole. Screwed it in the ground with a small rake handle. It went into my clay soil like a hot knife through butter--very easy! I understand why this product is "prison jump suit orange," so you don't lose it in the grass somewhere, but my application needed to be more discrete so I spray painted the top of it black. This is a solidly made product at a good price. I highly recommend this product.

The coating on this is great and it feels very sturdy. I also liked the visibility a lot. It was fairly easy to put in, even though I couldn't use my impact driver with it. However, when I increased the tension over time on the ratchet straps, eventually this started pulling out of the ground. I'm not sure if I exceeded the 125lbs rating. I very well may have. I put it in straight down and it didn't swivel under a decent angular load. I ended up getting the 20" disk-style ground anchor. They swivel a ton more, but they don't lift and they can be driven into the ground with an impact driver.I think you should get this if you don't need a ton of tension. Maybe for a small tree or to hold something down during a hurricane. But if you plan on putting a lot of tension on it, this curly-loop style of product doesn't cut it.

My first attempt to drive this in the ground didn't work. I'm pretty sure it hit a rock about 8 inches down. The top would rotate, but then return to its previous position when I let off. I had doubts. Then I moved it to a second location and was able to drive it all the way in. It wasn't very easy, even when I didn't hit an obstacle, but that is due to physics, not a fault in construction. This may seem obvious, but I found it easiest to drive into the ground by sticking a large screwdriver horizontally through the top and twisting it. Oh, and it helped to add water to the soil.After getting it in the ground, I secured a cable to the top of the anchor. Even after tightening a couple of turn buckles, the anchor hasn't budged.

definitely worth the price, easy to drill down

I bought this to help level a leaning fence. I hooked a ratchet strap to it and the fence and pulled it level. I'm not sure how much pull was on it, but given how taught the strap was, it's say it was pretty decent. This anchor didn't even flinch. The build quality seems pretty good, and very simple. The helix looks like is made from about a 3/8" diameter round rod with a point on the end. That's welded onto the top plate. The hook is held captive in the top plate so it cannot come out. It was very easy to put in the ground, which was damp with all the rain we've been getting. I could go about halfway down by hand, but then I needed to put a bar thru the loop on top to get it the rest of the way. I'd recommend driving it all the way down to the top plate so you don't bend the helix. Once it's in, it's very solid. I haven't removed it yet, but I imagine it will come out easily.
