"It has a genius design of having you softly screw-in this silver screw to the right, to make it go upwards. This will tighten its hold and make it able to fit literally any desk, no matter how thick it is. Most cupholders on Amazon have a clasp style that just sticks on by way of kind of forcing it on, and sometimes, the desk can be too large. With this design, that is no longer an issue."

Thank you David for this amazing shot of the Cup-Holster desk mounting cup holder.
