Designed for the monitors featured here but uses the standard VESA 75x75 mount type. The monitors can tilt up and down as well as left and right. The stand is very solid and mostly metal, the back removable parts are plastic. These back parts are removable to allow cable management through the stand. 

It is 17" from the middle of one mount to the other and ~11" from the bottom of a mount to the ground. 

The stands are used but show little signs of wear.
