FPS 6 Duckbill Earth Anchor Cable Stakes 20'' and 1 Duckbill Stake Driver

I used them to anchor a greenhouse. They exceeded my expectations!! We live along the coast where it’s always windy.

I have rocky terrain, but was able to get these pounded in. The metal spike could be stronger, as I would hit come rocks along the way, need to pull out, and start over in a new spot. The metal rod would be bent so I'd have to straighten it before giving it another go. If you're ground isn't so rock I'm sure this will work fine. Maybe go up a size/width if you're ground is hard/rocky. Once the earth anchors were all the way inserted, it seems pretty impossible to get them out. They are in there! Happy with them. Using them to stabilize/hold down an RV-like structure from wind.
