This is the only mount that meets my specific needs. Hole for grommet with mount for three monitors 27" apart. The brackets on this unit are strong so they don't sag, as I've had issues with another type of triple bracket in the past that had a lot of hinges. the bracket sags as soon as a load (monitor) is placed on it. This setup completely solves this problem. The site extends to other monitors so some work is needed to make it perfect, but all the settings are there. I've seen some reviews saying external monitors were lower. This is an adjustable refill that is the same as when I first assembled it. saw another review that said it doesn't hold the monitor, it kept moving. This is also adjustable, but you have to remove the plastic covering over the friction nut to tighten it (yes I had to tighten them all on my unit). up to 3 27" in landscaping, but that's a bit conservative. I have a few inches left on the ends of my arms with 3 27" Dell monitors. I highly recommend this monitor mount.
