This mount is engineered for the realities of off-road abuse, river impact, and jobsite vibration. The polyurethane strap conforms to uneven tube surfaces for unmatched grip, while the TwistLock interface delivers positive engagement you can feel the moment you twist your drinkware into place. Because the Bar Mount holds the locking base itself—not the cup—your drink stays upright even when the vehicle is leaning, bouncing, or off-camber. This is the simplest, cleanest way to add a no-spill drink station to any tube chassis or round surface.
