Monitor Stand to Attach to Desk

[jbd12345]

First of all, sorry if this is the wrong category I wasn't too sure.

I have two PC monitors (VESA compatible) that I would like to have on a single stand. I have seen many that stand on top of a desk like a normal monitor stand, but I would like to, if possible, get one that could clip onto the back edge of my desk as shown in the pictures. I know it is a long shot but does anyone know of such a stand?

My son uses this one .... he drilled thru the desk for security though it stood from it's own weight. he has a 1920 x 1200 and 2560 x 1440p
