Mayne No Dig Ground Anchor - 3.75in x 2.88in x 26.75in - Includes Lag Bolts (5) & 20″ Rebar (1) - Galvanized Steel (580D)

A while back I was looking out my front window. Just in time to see a big blue Amazon truck back out of my neighbor’s driveway, knock over my mailbox, and go on it’s merry way. Amazon may pride itself on their eco-conscious electric vehicles but let me tell you, my local air quality was not good with the amount of bad language that ensued.So, off I went to the local big-box store in search of a new mailbox anchor. That Amazon driver really got his money’s worth, by the way … the mailbox post was bolted into one of those anchors that has a post cap welded to a two-foot spike. He hit the box hard enough to break the anchor apart at the weld. I really hope he damaged his truck. Anyway, I couldn’t find what I wanted locally, so I grudgingly ordered this anchor — from Amazon.Irony aside, this anchor is solidly constructed and doesn’t seem to have the points of failure that the old anchor had. I was able to screw it into the ground in about 15 or 20 minutes. The supplied piece of rebar is a bit short and I used a longer piece for better leverage. I also had to use a scrap piece of 4x4 and a sledgehammer once or twice to get through some hard spots. Still, given that our ground is like concrete, this actually went pretty well. The last time I did this, I had to use a power auger. This really wasn’t bad at all — in normal soil I think it would be a piece of cake.Once I had the anchor in place, everything else went smoothly. I cut a piece of 4x4 and cable tied my post level to it. I had to bend the legs of the anchor a bit to get the post straight front-to-back. The lag screws that are supplied with the anchor looked a bit cheap, so I used some 2” stainless lag screws and 1/4” washers that I had on hand. A drywall screw worked well to make pilot holes for the lag screws. I used a cordless impact gun to drive the lag screws home, and a couple more lag screws to attach my mailbox — one of those one-piece plastic deals — to the post.The resulting installation feels sturdy. I guess we’ll see just how well it stands up to my neighbor’s next Amazon delivery.

Wow, moving bites. Was not sure how I was going to manage putting in a rural mailbox. This was the solution. I am a 63 years old female 4'11". This was moderately difficult due to what was in the ground. I was able to do it. Once in The ground the post went up quick and easy. I am not strong. I could not have dug a hole. The way this screws into ground was perfect for me.

I bought 3 of these to use for posts to hold up Liberty Garden hose reels. I used 2 Mayne ground screws for the #714 model of Liberty hose reel that would otherwise have mounted to a wall with fasteners at 16" o/c. They work great for that, as I will explain. I bought the 3rd Mayne ground screw for the #712 model of Liberty Garden hose reel, a single post mounted version hoping it would work just as good. I come find out that as I unwind and pull the hose from the reel, mind you these are rotating hose reels that I have rotated in the direction I wish to unravel the hose, that the whole assembly rotates the ground screw quite significantly. To put it in perspective lets say approximately 100 degrees of rotation. Then I have to rotate and screw the screw back to position. This 3rd installment was at depth with only the post above grade. The first hose reel works great as the two posts in the ground resist the torque, but with only one ground screw holding one post its not very resistant to torque. Basic law of physics demonstrated here today. Not Maynes fault for being an idiot and not thinking about the consequence of rotational torque for a one post design, but makes me question its ability for the intended purpose of a mailbox post too. Now I have to come up with a solution to solve the roating problem on the single mounted reel. These are great no dig solutions, but I wish they were availible in longer lengths, like 36-48", to get below possible frost depth as to avoid soil creeping ultimately leading to a leaning post in the end and/or to help out sandy/silt type soil anchoring. It was quite easy to rotate it and I probably could have gone farther if sold in longer lengths. In my case I have silty soil, which is basically a very fine sand. Its the same reason one needs to really go deep when screwing a beach umbrella in the sand. This was the longest 4x4 post ready earth anchor I was able to find other than ones that may require a 2" impact driving bit to install and a bracket would need to be used on top of it to support the intended loads.

Made installation of mail box easy!

What a time saver. No hole digging or concrete mixing. Works perfectly.

This product was purchased from Amazon. It claimed to be intact with some minor packing damage. Upon arrival, it did not include the piece of rebar. When contacting Mayne, they "mansplained" to me that this is only to assist in installation. After blaming Amazon, they said for a mere $15 they would send me the part. Obviously, a company that is highly concerned with customer satisfaction.

Used it to install the mailbox post 10+ year ago。 It still stands upright, no problem; and I would expect it to last 100+ year in the ground。
