Holds my big Yeti cup with no problem!
Big Ass® Drink Holder with Aluminum Clamp Mount
Great quality. Travel mug fists snug no matter the size. 20 and 30 oz. Yeti's fit perfect.
Easy to install and works great.
Works as expected. Keeps a firm grip on anything you place in there. Can be swiveled around to find the perfect spot. Worth the $. Recommend it!
