Question about Ergotron LX Monitor Arm with patented CF technology

I have mounted this arm on an existing bracket without any problems.
Ergo, you should also be able to easily mount another arm here.

Hoi, Hauserraphael08, wanted to ask you, did you get it right? I'm also wondering if you can install two 27 inch monitors with this model. I already have a simple LX arm and want to combine with that, but whether it works is the question. Greetings
