Review: 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. Review: Ergotron is a good choice for a monitor support system - Ergotron is a good choice for a monitor support system. One bit of information I always wanted to know and had a hard time figuring out when I went to buy one was what should I get? A desk mount, a wall mount, a dual monitor setup. After having used one for a few years now I can say with relative certainty in most cases you are probably going to want to get a wall mount if you can. I got a desk mount, and it works very well for me, but I also had to specifically find extremely heavy and sturdy furniture to mount it on. The usual particle board that everything cheap seems to be made out of is simply not going to cut it. The factor of stability comes into question even more prominently If you want to add one or, like I did, two extensions, because you are leveraging that weight even more. I'd be loathe to add another extension on the desk mount I have. As it is, I think its going to be sturdy enough to hold, but jumping up and down on it definitely isn't advisable. As far as two monitor setups go, if you want to do that plan it from day one. I was going to do that, figured I'd start with one and see how it went, and years later I still have yet to act on it. ## Features - Compatible with LX Arms: Upgrade your LX Desk Arm (45-241-224), LX Wall Arm (45-243-224) or LX Keyboard Arm (45-246-026) with a second extension to increase its reach an additional 9 inches; adding extension may reduce weight capacity; not recommended for use with LX Dual Arms - Simple installation: Easily and quickly add one extension to an existing LX Arm; includes 9-inch extension and end cap - Extra flexibility: Another pivot point allows for a wide range of adjustment, expanding use for a broader variety of individuals and applications - Neat workspace: Streamlined design accentuates any work area and clean cable management routes cables under the arm and out of the way - Built to last: Extensive quality testing ensures your display stays stable and secure; Ergotron products set the standard for quality with a 10-year warranty and expert technical support ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09T782YJ2 | | Best Sellers Rank | #616 in Computer Monitor Arms | | Brand | Ergotron | | Color | Matte Black | | Customer Reviews | 4.6 4.6 out of 5 stars (948) | | Date First Available | February 23, 2022 | | Is Discontinued By Manufacturer | No | | Item Dimensions LxWxH | 17.1 x 17.7 x 29.9 inches | | Item Weight | 1.32 pounds | | Item model number | 45-289-224 | | Manufacturer | Ergotron Inc | | Product Dimensions | 17.1 x 17.7 x 29.9 inches | ## Images ![Ergotron – LX Monitor Arm Extension – Add-on for LX Desk and LX Wall Monitor Arms, LX Keyboard Arm – Matte Black - Image 1](https://m.media-amazon.com/images/I/51gEvKxEdHL.jpg) ![Ergotron – LX Monitor Arm Extension – Add-on for LX Desk and LX Wall Monitor Arms, LX Keyboard Arm – Matte Black - Image 2](https://m.media-amazon.com/images/I/71C8XtcbhaL.jpg) ![Ergotron – LX Monitor Arm Extension – Add-on for LX Desk and LX Wall Monitor Arms, LX Keyboard Arm – Matte Black - Image 3](https://m.media-amazon.com/images/I/51uW7ZEmVGL.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Used to extend my monitor's reach (added to existing 2 LX extensions), sturdy *by B***W on February 1, 2023* 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.

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?
