It’s perfect for anyone looking to stack dual 49-inch monitors vertically while maintaining adjustability and stability. Pros: Heavy-Duty Build: The extension arm is built to support large monitors securely, with no noticeable wobbling or sagging, even with heavier setups. Height Adjustability: The height adjustment feature works smoothly, allowing you to customize the position for an ergonomic viewing experience. Compatibility: Designed specifically for the MA20P-S arm, it integrates seamlessly and supports VESA 100x100 mounting standards. Clean Design: The black finish looks sleek and professional, fitting well in any office or gaming setup. Space-Saving Solution: Vertical stacking frees up desk space while providing an immersive multi-monitor experience. Cons: Accessory Only: This extension arm cannot be used on its own and requires the MA20P-S Single Monitor Arm, which might limit its appeal to first-time buyers. Assembly: Installation can be a bit challenging, especially for larger monitors, and might require a second pair of hands. Overall Verdict The ULTRARM Heavy Duty Extension Arm is an excellent accessory for those who need a vertical dual-monitor setup. Its sturdy design and adjustability make it a great investment for professionals or gamers seeking a reliable and space-efficient mounting solution. Rating: 4.5/5 Highly recommended if you already own the MA20P-S monitor arm and want to elevate your workspace with a durable and stylish extension arm.

Only Bought this Arm Because I didn't Believe some Negative Reviews
I had been toying with picking up a dual mount arm for a while and was eyeing the this Ultrarm. I was breezing thru the reviews again and I saw a negative review that made me have to order and try myself. He was gracious enough to share a picture and review that rubbed me the wrong way. Complaining this arm will not hold a 57" when others say they do without issue is a problem. Then to show a picture of it leaning when he is trying to mount a 1500/2k monitor to a Dollar Store style desk. I mean, come on, spend a few bucks and get a decent desk top. I suggest a real butcher block 1.5" thick minimum. Not only that, he's got the mount at the tip top of the pole. Unbelievable... If you are not mechanically inclined, please get some help. While, I didn't go with the 57", and instead upgraded to the LG 45 5k2k, I have no doubt that this mount will hold it and the other positive reviews with 57" displays are truthful. I've had many monitor arms and this one is probably the best I've had. The finish is fantastic although its hidden so doesn't matter I guess. The one con is vague instructions. But I've come to terms that instructions will always be unclear on amything I order from Amazon. It was easy enough to figure out having done many mounts. Anyways, don't usually leave reviews but there were a few negatives that I just didn't believe and it irritates me when people blame their lack of common sense on the products because folks may decide on someone who has no business leaving a review.

Stacked 49's
Stacked 2 SAMSUNG 49" Odyssey G93SC took some effort to get them to line up. Directions are poor on how to put the whole assembly together. Nothing written and any videos online are in Chinese I believe. So you have to build by pictures. I found it easiest to slide the monitor onto the arm and then mount the arm into the base. After it is put together it is very sturdy. I used the clamp does not feel cheaply made. You cannot push the arm down until the monitor is mounted. But I would recommend as long you some mechanical aptitude to get it put it together.

Great
I am removing one star only because the channel for cables could hardly accommodate my wires. Granted I used all of the monitor ports, but still.

Great extensions for an already great mount
Update 21 Feb 24: So the seller contacted me even though I gave the product 5 stars. They sent me a picture and instructions of how to configure the mount to increase the spacing of the 32 inch above the 57, so there is now plenty of room for a camera to be mounted on the 57 underneath the 32. Apparently you can actually use the extension arm from the bottom monitor to extend the top monitor. This means the bottom monitor would only be connected via the gasket arm which means you will have limited options to position, so there is a trade off as there is no perfect mount. However, this is the exact configuration I needed and I do not move the bottom monitor at all. Now it is the perfect mount, and I am excited when I can afford to get a second ultra wide to throw on top. Awesome seller, and awesome product. Original Review: So I got this to add a second monitor to the ultrarm mount holding my Neo G9 57". For now I am throwing a 32" above the 57. There are a couple things you should be aware of if you are doing this. There is not much room left between monitors and you will need to stagger them if you want your camera mounted in the middle. My 57" has to be near the lowest point and the 32 is at the maximum height to be stacked. I plan to throw a 49" in place of the 32 when I can afford to upgrade, which would be a little more forgiving since the monitor would take up less vertical space. Adjustment on the 57 was tough tough due to the weight, but the 32 is pretty easy to adjust as it doesn't weigh as much. I would highly recommend this and the base if you have an ultra wide and want to either do a dual ultra wide, or throw any 32" or smaller monitor above an ultra wide.

Solid mount, Easy to install, VESA mount a bit large for my Samsung monitors.
Great product. I purchased one for my two Samsung Odysseys ultra-wide monitors, at first I thought the VESA plate is causing the monitors to tilt downward, (The VESA plates are too large at the top as the monitors have a rounded back area and the VESA Plates should fit inside the circular recess, I guess) but I noticed I was still learning how to adjust movements. Overall great quality and functionality, my space looks clean and saves desk space.
