KdgardenPremium No Dig Ground Anchor Black U-Model Screw in Post Stake 27" Long Anchor Fits Full Sized 4"x4" Posts, Great for Mailbox Posts and Fence Posts

Used these to put in a 12' x 6' trellis on my patio. Easy to "screw" in and sturdy as concrete in posts.

Thank you

I had 2 issues with this anchor. First the bracket was about a half inch larger than a 4x4 post. I wedged another small board in it to make a better fit while I adjusted it. 2nd, the leverage bar isn't long enough or strong enough to tighten it all the way. I used it and a breaker bar with a long pipe to get it down so it's no big deal. 3rd the screws are small. They are long enough but the heads will almost go through the bracket holes. Overall it is a awesome product and saved me from digging a new hole due to some nice person ran over my mailbox and broke it off at the ground.

Does not work in sandy locations. When 5 inches from done, it came out when leveling.

I use it to anchor a diy kids basketball pole , which is very easy comparing to use a concret base, but I would expect this kind of anchor is not suitable for full size basketball pole, since it it hard to get heavy things level and hold it as level

I had no idea how massive this post anchor was!!! It's super heavy duty!!! Very impressed and glad I purchased it!

easy installation, very tough product, will last many many years....

I'm not sure where you find a "full sized 4x4 post", but this does not fit your standard 3.5"x3.5" 4x4s without a shim. It looks like there are other options available on Amazon that are supposed to be the right size. Choose one of those.I don't know about the sturdiness of the anchor.
