Designed for bigger insulated cups, plastic water bottles or even your reliable steel coffee cup, the Level Cup XL keeps your drink upright, regardless of the conditions. This kit includes a long arm that can accommodate any B-size mounting base. This gives you the flexibility to put your cup anywhere you need it. 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.
