30 inch Ground Earth Anchors with Rod, Arrow Shed Anchor Kit for Securing Camping Tents, Sheds, Swing Sets, Greenhouses – Easy to Use, 6-Pack Heavy Duty Tree Stakes Retaining Wall Anchors

We love these as we live on shale rock and they are absolutely the toughest tiedowns in any wind.

These are great works well and will hold ur green house

These anchors work well, but you really need the metal rod that is used to install them.

Went in fairly easily in red clay soil. Couldn't pull it out with a jack so I'm not afraid of the shed blowing away in a storm. Only suggestion would be to move (twist and pull) the driving rod after every couple of hits to keep it from getting stuck in either the anchor or the soil. If you have sandy soil that may be different.

These are very heavy duty compared to others. I put 20 into ground containing 3-6” size rocks. Not a single one broke which was better than others I have used in the past. My only reason for not giving them 5 stars is the receiver is a little short; it’s very sturdy but needs to be a half inch longer to stay in-line with a pneumatic driver.

Pleasantly surprised how great these work

I used the original product 30+ years ago. They were called mantarays. They were way bigger for heavy soil stabilization reinforcement anchors. I know how to use them. They work.

This ground anchor set is really extremely practical! The installation is easy and simple. Thanks to its unique design, it can be easily inserted into the ground, saving time and effort. Its tensile resistance and load - bearing capacity are also excellent. It hasn't disappointed me in the several times I've used it. There are 12 ground anchors in one set, which fully meets my usage needs.
