Musicians, DJs, podcasters – this little accessory is a game-changer for keeping your drink handy and safe. It's a simple clamp that attaches securely to any microphone stand, drum stand, or light stand with tubing between 3/8\ and 1\ in diameter (which is almost all of them). The clamp has a sturdy, adjustable screw to tighten it in place. The cup holder itself is lined with soft, squishy neoprene rubber. This does two awesome things: first, it grips your cup or bottle so it doesn't rattle or fall out, and second, it acts as insulation to keep hot drinks warm and cold drinks from sweating condensation all over your expensive gear. It holds cups with diameters from 3 to 3.25 inches, so it fits most coffee mugs, soda cans, and water bottles. No more balancing your drink on a wobbly speaker or risking a spill on your mixer. It's a cheap, brilliantly simple piece of gear that every performer should have on their stand. From On-Stage Stands, a trusted brand in the music industry.
