Cant make up your mind between the horizontal-mount and vertical-mount versions of our 2-cup holders? You dont have to. The Angle Mount Cup Holder can attach to either, and anywhere in between. A RAM Mount socket arm gives this cup holder the flexibility to match any mounting surface youve got. Like all of our cup holders, it attaches with a powerful-yet-simple-to-use SeaSucker 4.5 vacuum mount, which means you can put it where you need it, when you need it. The cup holder inserts remove for easy cleaning and can be swapped out for our Small Dry Box (available HERE) for safe keeping of cell phones and other items you dont want to get wet.
