Review on Enhance Productivity with Mount-It! 4 Monitor Stand: Quad Desk Mount for Multiple Computer Screens, Adjustable Arms, VESA Compatible - Perfect for 19-32 Inch Monitors by Tiara Andrews

Please note: Make sure the table top is thick. If it is thin, the weight of 4 monitors may be affected a little. Clamp or screw gives you options. If you have a glass table top don't use it, never use a clip on/through mount installation, you'll need to find a table stand that isn't as sturdy as this one. Spaced and lined up for OCD types too. The built in cable management is great, again for OCD guys like me. The monitors didn't fall off at all. I love this stand.
