Fence Post Anchor Ground Spike Metal Black Powder Coated 36 x 6 x 6 Inches Outer Diameter (Inner Diameter 5.5x5.5 Inches), Pack of 4

Finally did my project and these worked beautifully they came with bolts to tighten which was great!. Used it to make a freestanding trellis for some jasmine.

Super impressed with these Fence Post Anchor Ground Spikes! Installation was a breeze - no digging or concrete needed, just hammer them into the ground. Perfect for anyone who wants to skip the hassle of traditional fence post setting.They've held up great so far - our pergola feels very secure, even in windy weather. These spikes are a lifesaver if you have rocky or hard soil where digging holes would be a nightmare.Just keep in mind the post size limitations and be sure the ground isn't too soft. Overall, a fantastic product that makes fence installation fast and easy!

If you're looking for a reliable and hassle-free way to secure your fence posts, I highly recommend the Fence Post Anchor Ground Spike Metal Black. It’s a high-quality, cost-effective solution that gets the job done quickly and efficiently.

You have to provide anchoring or additional bracing

Used to make a shade fence for the pool pump. Perfect for keeping the wood out of the ground and very sturdy.

Good

Spike is 18" so they drive into the ground easily. Spike/box welds look good and should hold up to snowplow hits. Road salt has been the demise of other spikes I've tried. The paint on these looks like it should resist corrosion for a while. 4x4 fits perfectly in the box. I don't use the tightening bolts since I sometimes need a quick mailbox swap after a snowplow hit. If I remember I'll update this post next Spring on how the spike performed.

I have used these as part of my perimeter fence, the base for chicken coop posts, and the base for pergola post.The stand alone post work well for my 5ft fence. Some wood post were easy to fit and some were not. One batch of 4x4s I got from home depot were not fully dried out, and they would not fit into these spikes easily. I didn’t think it would be a problem until I tried using them. That was only 3 4x4s out of the 15 4x4s I used with these.Using the spikes as the base for my chicken coop and pergola post was easy! Unfortunately I had to move my pergola a couple of months after I built it. Removing the spikes was a little difficult, but no where near as hard if I had to dig up the post. I will definitely use these again for future products
