    Q:Can the post base be adapted for use with lumber that measures 3.25 x 3.25 inches?
    by|Aug 2, 2022
    1 Answer
    Answer This Question

    A:  You screw in the tightness of the base, so you can adjust some here. You could always use some shims in there for gaps too.

      Q:Will this support a 4’ farm gate that gets minimal use?
      by|Jun 27, 2021

      Answer This Question

      A:  No. This is not intended to support a cantilevered load. Great for mailboxes but that’s it.

      by|Jun 28, 2021

      A:  That's a minimal description. Solid fence or wire ? What's the gate made from and design ? Is that 4' high or 4 ' long ?What's the soil ? ... The post holder will easily support a 8' post. Any trouble you'll see will have to do with leveraged torque applied to it. It tapers and therefore lacks the resistance to prevent it from leaning with time. You could probably offset this with the addition of a guy wire to the post.

      by|Jun 29, 2021

      A:  I used this product to hold a 50' light weight hose and its works fine. Would be reluctant to use it to hold the lateral weight of a gate.

      Q:Can this be used to build a 3 foot high 6 foot long sea wall if I put one every 2 ft
      by|Sep 2, 2020

      Answer This Question

      A:  Assuming you intent is to build any kind of functional sea wall, no, these will absolutely be inadequate.

      by|Sep 4, 2020

      A:  Am not an engineer but my experience and personal knowledge tell me that this post 1) lacks the strength (i.e. width) and depth to hold "a sea wall"; and, 2) it will rust quickly from the water/moisture, especially if it is salt water. Bulkheads are normally built with marine grade wood post (round or square) that are driven or dug into the ground 3' deep or more. The square post are usually 5" x 5" PT lumber; suspect the round post are at least 5" in diameter. This post is meant for a mail box post or, as I used it, to hold a 4" x 4" post holding a garden hose bracket. Even when used in that manner the post wobbles.

      Worked well
      I used this size post to improve on a grape arbor. The length was perfect for use with 6' 4x4 treated posts. It pounded in easily using a sledgehammer and using a piece of 4x4 slightly taller that the sleeve of the post to pound it in.

      This made planting a fence post, in an area where digging and drilling was impossible, possible. The post was straight and level with very little effort.

      NOT recommended for use with fences taller than 5 feet
      NOT recommended for use with fences taller than 5 feet. Made in Vietnam, thin gauge metal twists with my bare hand. If stake sunk into concrete and 4x4 post is only 5 feet then this system might be worth a try. A little swinging during wind storms better than posts rotting after 15 years

        Not for heavy wind areas or heavy duty application
        Easy to install and held up great for a few months. But then we got a few wind storms (24 mph) winds and even with the one inch spacing between pickets, the spikes snapped clean at the base. Avoid these if you are planning to put up in high wind areas. They have held up in an area that I used mesh wire, as the wind passes through. But these are not built for heavy duty applications.

          By far the easiest way to install a curbside mail box. Simply pound the Groundmaster in, insert a 4x4 post and tighten the bolts. Shim if you like. Good and stable for 20 years.

          Worked for me but.....
          These worked for what I wanted to do but let's see how long they last below ground. Also this product certainly does feel lighter than previous versions. It helps to cut a section of post, 8" and install it securely then pound down on the section of post. This helps from destroying the product.

          Worthless - Save Yourself a Headache and Use Concrete
          These are much easier to install than digging post holes and using concrete, but if you are building a fence that you want to stand up any amount of wind then use concrete. Also, they rust very quickly. I purchased 9 of these anchors to build two fences. I used 4 anchors for one fence and sunk the 5 anchors for the second fence. Before I could put up the second fence a wind storm came trough and blew over the first fence. Three of the four anchors broke clean off at the joint and one was severely bent. Not wanting to face the same problem with the second fence, I dug up all 9 anchors and tried to return them to Home Depot. Home Depot would not take the three broken anchors or the bent one, and of the other five that had just been in the ground (without a fence), three were too rusted for them to take back. Too rusted? I've had them for three weeks? I am seriously disappointed with this product. I read several reviews for Oz-Post and was very impressed with the technology. I asked a store associate for Oz-Post and they recommended this product. From what I have seen, the quality of this anchor is nowhere near that of Oz-Post. These anchors have poor welds and poor corrosion resistance coating. I would definitely NOT recommend this product.

          Real good solution for setting a post where I would not have been able to dig out 2.5 ft in a densely rooted area. The time (and agony) saved more than offset the cost.
