SELEWARE Heavy Duty Ground Anchors Tent Stakes Set of 4 Camping Stakes Trampoline Anchors Dog Tie Out Stakes, Twist Rod Included

Sturdy anchors. East to install with a drill even in rocky soil. Works great with a wooden swingset.

We got these anchors to hold down our kids trampoline. Really easy to install and comes with the tool needed to install. You need to buy good 1 inch ratchet straps.They work really good. During the hurricane we had wins 50+ miles an hour and gust 70+ miles an hour. The trampoline did not move stayed in place. I wish I would’ve bought these years ago and maybe I wouldn’t have to have replaced the trampolines after storms. LOL!

These worked well but did not penetrate rocky/gravely soil. Excellent in dirt surfaces.

Came with everything you need to install them works really well! Using them to hold down an outdoor curtain for my patio at the edge of the cement really happy with them

I got these to hold down a plastic greenhouse, thinking they would be light weight and a little on the flimsy side, like most tent stakes. Boy, was I surprised. These are thick, heavy weight units. They more than worked for what I needed them for. I also used them to hold down the tarp over. I would buy again.

Well made. Worked for what I needed.

These stakes are heavy duty with a great and useful head design. The spiral shank screwed well into the sand and held on a windy day. We used them for a shade tarp at the beach.

I used a half inch drive battery impact with a 14 mm socket. Installed in rocky upland soil that was dry. The impact drove all four flush with the ground in only a few seconds. One anchor hit a rock about 4 inches into the ground, reverse backed it out without issue.I was surprised and impressed, driving anything into the ground in the hills is difficult. Obviously won't drill thru a rock, but definitely worked its way around rocks.
