ErgotronLX Monitor Arm Grommet Mount – Add-on for LX Dual Desk Monitor Arms

Ergotron is one of the first pioneer of monitor arms (and part of the original VESA consortium)with that, I have an old LX arm that needed a grommet mount since these don't come with LXwhere as all Chinese brand (huano, NB, and such) all come with grommet mounts as well as c-clamp, for cheaperI understand you get what you pay for but in this case, I had to pay extra for what should've been included in the first place...I'm a little grumpy because of thisotherwise it is easy to swap and install

Worked great for surface mounting anywhere. I had been limiting myself for 5 years with the other mount. Glad I finally bought it

That is the correct grommet mount for the tall pole LX Ergotrons.Don't mix it with the short one.
