Used to extend my monitor's reach (added to existing 2 LX extensions), sturdy

I wanted to be able to secure my monitor to the wall in my RV and have it extendable out to the dinette or bed. I can't do that, so I have a pole right next to the wall that it is attached to. I added this extension to my Ergotron LX dual monitor stand I already had, making 3 extensions plus the adjustable arm that the monitor attaches to. It works fine, though the weight is enough that even with a very sturdy pole I got as the base, it still flexes a bit and bounces with the monitor fully extended 38-40" from the pole. But that isn't the fault of the arms, it is the pole that flexes (which isn't surprising, given the weight of the monitor is 7 lbs at 3 feet out from the pole). I think you'd need a pole that was really short, or could also be clamped at the top. My pole is nearly 4 feet tall and very solid (thicker than the original short pole that comes with the LX dual stand), with dual clamps, near the bottom and then maybe halfway up.

Awesome product

Ergotron products are worth every penny, they are so well-built. I did a new desk set up and was so happy I could add an extension arm!

Works with HUANUO Dual Monitor 'tree' arms

Awesome for those like me who use a 22" high fps monitor with a 27" 4k monitor. Both of mine are mounted on the HUANUO Dual Monitor Stand and a fairly wide desk, so to get them positioned properly I needed at least one of these. Its super nice to be able to pull the gaming monitor super close when actually gaming while keeping the other monitor farther to the side and not have any visual overlap while sitting at the desk!The only possible downside is that the little cap doesn't snap on where the original HUANUO arm connects to this extension. it appears the Ergotron has a shorter cylinder... but who cares about that right? I'm making those 360 no-scope shots while watching whatever I have on the other screen between skirmishes :D

Works with "LX Dual Stacking Arm" (45-248-026)

I wrote support and asked if any arm extensions worked with the model I have, the "LX Dual Stacking Arm" (45-248-026). They said no, nothing they have is compatible with it. I disregarded that and bought this anyways, and it fits and works perfectly. (This 45-289-026 "LX Extension for LX Arm".) The 3d files on their site show the measurements line up too, so I don't understand why their support tried to lose them a sale.The other extension arm is a little longer, but the hole size is a little different, so be careful to get the right one for the stand you have.

Extends the reach of my Amazon Basics Monitor Arm

Works with the Amazon Basics monitor arm as it is made by Ergotron. Extends the reach beautifully, no sag.

Only get ONE

You can theoretically use more than one but the leverage gets worse and worse.

A little pricey but perfect for the job...

This extension arm was a little pricey for what it is, but it works great for exetending the monitor arm. I have the mount on the wall next to a recliner with my gaming monitor. With this extension, it swings right out in front of me so I can play games while sitting in my recliner with the monitor just right in front of me.

If I ever need a hip replacement, I want one from this company.

This is without a doubt one of the best products I have ever purchased in my life. I call it the ‘Terminator arm’. It’s incredibly solid and heavy duty and it makes every single day at my computer so much more pleasurable. For intense comptetitive FPS gaming, it’s the perfect solution to getting my heavy 27” gaming monitor at perfect height and distance no matter how much I move my seating position.I can not stress how solid this thing is. If you told me it’s a part that is an upgrade to my German car’s suspension I would have probably believed you.
