Ergotron MX LCD Monitor Wall Mount

The listing

Lightly used adjustable monitor wall mount for heavy (14-30 lbs.) LCD monitors. Must be mounted using wall studs, so keep that in mind when choosing a location. Includes all parts and instructions. New price $256 dollars. Very nice solid arm, I am still using one for my own monitor. Selling because my wife's monitor wasn't heavy enough so I had to buy another arm.
