Used Ergotron Monitor Arm - Amazon OEM As shown in images 14, 15, 16, and 17, the arm's base is slightly misaligned due to being mounted from the side of the desk, resulting in a gap. While there were no issues with its functionality, I didn't move it up, down, left, or right much, and used it fixed in place as shown in image 14. The first image shows everything included. I believe this is everything. There may have been spare screws, etc., but only what's in the first image is included. The monitor light in image 14 does not work. Monitor arm only.
