    Q:I am wondering if this would work with mesh shade fabric. I have installed the fabric over my existing chain link fence for privacy. I would like to add more height to the fence and then add the mesh shade fabric (which is not a heavy material).

    Answer This Question

    A:  Hello, This item is designed to extend the height and hold the weight of wooden fences and chain link fences. The weight of the fabric is probably much less. You'll have to determine if it's correct for your project as we cannot give specific project recommendations. Thank you for your inquiry.

      Q:Is this strong enough to extend a gate post?

      Answer This Question

      A:  Hi, and thank you for your question. We apologize we do not have the data to answer this inquiry at this time. For installations like a gate that are going to have regular movement and sudden short spikes in force applied to that post, we do not recommend the use of a post extender. Thank you for your inquiry.

        Q:Would this work to extend a 3 foot high post to 9 feet for use as an anchor for patio/bistro lights? Just wondering if this will support the tension needed between anchor points.

        Answer This Question

        A:  Probably not. You'd need 2 pieces and it would be flexible.

        by|Nov 22, 2022

          A:  Hello, This item is designed and recommended for use for one extension up to 3 ft. We do not recommend putting an extension on top of the extension. Thank you for your inquiry.

                Easy to attach; made a straight and strong extension with a barely noticeable joint. I only needed 20", not the full 3', so I bought a metal-cutting blade for my sliding compound miter saw that made shortening 5 extension posts a snap. (IMPORTANT: the top of the posts receiving the extensions must be flat and perpendicular for a good connection — I used a 2 3/8" metal-post-to-wood bracket as a guide and an angle grinder to trim a couple that had been raggedly cut with a hack saw).

                The Oz-PostAdjustable 3 ft. Galvanized Steel Post Extender is a great idea and generally works fairly well, but IMHO, it is slightly under engineered. The biggest improvement would be the addition of a tacked washer to the top washer to prevent the horizontal slip which happens when tightening bolt. Since installation was so easy to do, I am going to try to glue the carriage bolt to its washer with construction cement. My base post are plumb and factory cut. Since these posts are shipped, I suggest to use reinforced shipping tape rather than regular shipping tape on the parts and on the shipping carton. Five of eight pieces were missing from my 3rd post. All shipping tape was broken.

                  I just installed these onto my existing terminal posts and you really can't tell they didn't come that tall in the first place.They were easy to install and only took a few minutes. Now, I can use the existing posts for what I wanted to now, a taller fence.

                    The use for this post is limited. If you are trying to extend the post for fence purposes, this might work. However, if you look to extend the post to attached something higher than what you currently have, it will not work as you desired. The bolt used in this 3ft post extension it is not strong enough to withhold any pulling force, specially if wind is added to the mix. I need to return this product. It did not provided the function that I desired.

                        So much faster and easier than digging out the chain link fence posts. I cut them to 6’ for the pickets I got. Very cool to know these exist!
