ErgotronLX Monitor Arm Extension – Add-on for LX Desk and LX Wall Monitor Arms, LX Keyboard Arm – Matte Black

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!

If you need to extend your mount this is the part you need. Works well!

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.

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

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

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.

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.

Product does not fit their HD arm. Vendor did not care that first arm was delivered to wrong address never to be seen again and I was beyond return date when I found that the extension did not fit. Now I am stuck with a $300 plus purchase that does not fit my desk and is useless to me. First Amazon denied return, then authorized on appeal and then reversed authorization claiming their customer service rep was not authorized to accept return. Very dissatisfied with customer service from vendor and Amazon. As a loyal customer I think I deserve better treatment. As a retiree it is an expensive lesson.

Hält super, gerne wieder. Habe zwei Mal verlängert, um den Bildschirm knapp halben Meter höher zu hängen.

Hab mir 2 dieser Verlängerungen für meine Amazon Halterung für 2 Monitore geholt.Sie passen auf anhieb, also keine Probleme weil es 2 unterschiedliche Herstelle sind.

Przedłużka jest wyświetlana na stronie sklepu jako pasująca do samego stelaża "LX HD stelaż do monitora - uchwyt stołowy do monitorów do 13,6 kg" - a nazwa "Przedłużenie LX" sugeruje, że jest to część zestawu.Nic bardziej mylnego. Ramię na inną średnicę nasady (z jednej strony za luźne, z drugiej zbyt wąskie). Dodatkowo sam stelaż dźwignie 13.6 kg - zaś przedłużka nie więcej niż 8.1 kg.

Robusto y amplía el rango de alcance del brazo.. 100% recomendable.Solo un detalle.. ojo con la palanca que pueda hacer en el tablero si éste es "fino".. en caso necesario, recomiendo reforzar el soporte con un trozo de madera más ancha para que el monitor no se mueva en caso necesario.

Super useful! The extension allows the arm to fully double back on itself really letting you use a cintiq as a proper vertical monitor and a drawing surface.
