- This Hill Car Cup Holder: Designed for versatility and convenience, our cup holder features a locking function to keep the top bracket secure and prevent movement. The extended height of the top bracket accommodates taller cups, while the rotating mechanism allows for easy size adjustment without pulling. The thickened base provides robust support for heavier items. - Strong and Non-Shake Design: Crafted from high-quality ABS material, this cup holder extender is built to last. The rotatable expansion base extends from 2.56 to 3.93 inches, ensuring a secure fit that eliminates shaking. An impact-resistant silicone lining on the inner wall protects your cups from collisions. - Enhanced Material Features: We’ve upgraded the top bracket to support larger and heavier cups effectively. The height has been increased from 3.29 inches to 3.99 inches, addressing the issue of short brackets. Additionally, the reinforced design at the bottom of the top bracket ensures stability under pressure from heavier objects. - User-Friendly Installation: 1. Insert the base into your car’s cup slot. 2. Tighten the knob for a secure fit. 3. Unscrew the turning axis knob to separate the cup holder. 4. Adjust the bottom knob to fit your cup size. This 2-in-1 cup holder expander is compatible with most car cup slots but may not fit certain sharp-angled designs. Please verify the product dimensions before purchasing. - Practical Applications: Ideal for road trips, daily commutes, or even as a travel accessory, this cup holder ensures that your beverages stay securely in place on any journey. Perfect for coffee cups, water bottles, or soft drink cans, it offers a reliable solution for all your drink-holding needs while driving.
