Variable Adjustment VESA Adapter Kit — Tool-Free Monitor Alignment for Triple Monitor Stands

Seems like monitors nowadays have a recess in the back for the stand that comes with them. These mounts DO NOT fit inside that recess. You are expected to use a bunch of washers to fill the recess, and they don't supply long enough bolts to make that work. I ended up 3Dscanning the back of my monitor and then creating an insert that was 3D printed to fill the recess in the back of the monitor, then ordering longer bolts in order to actually use these.

Exactly what i ordered. Makes triples such mych easier to line up!

They do not work with every style of monitor. You pay a huge amount for trak racer products and you get to pay for shipping. I had to customize these to fit my monitors
