Designed for bigger insulated cups, plastic water bottles or even your reliable steel coffee cup, the Level Cup™ XL features a gyroscopic self-leveling system that keeps your drink upright, regardless of the conditions. This kit includes a Level Cup XL that has an integrated single-socket arm. This cup holder can attach to any B-size base or RAM® Mounts B-size ball accessory. The oversized opening cradles the biggest of gulps and the adjustable bottom piece moves up and down to accommodate taller cups. The rubber feet flex to fit various size cups as well. RAM® Mounts has refined the self-leveling action to keep your cups full.
