Can't make up your mind between the horizontal-mount and vertical-mount versions of our 2-cup holders? You don't have to. The Angle Mount Cup Holder can attach to either and anywhere in between. A ball-and-socket joint gives this cup holder the flexibility to match any mounting surface you've got. Like all of our cup holders, it attaches with a powerful-yet-simple-to-use SeaSucker 4-1/2 Inch vacuum mount, which means you can put it where you need it, when you need it.
