RAM Mount Open Socket Arm System

B-Size refers to the industry-standard 1-inch diameter rubber ball used in the RAM Mount system. This is the most common size for lightweight electronics like GPS units, smartphones, and small tablets, ensuring compatibility with a vast ecosystem of other RAM components.

The included round base is designed for flat, rigid surfaces. If you need to mount it on a curved dashboard or tube, you will likely need to purchase a separate adapter or a different base style compatible with the B-Size ball.

The rubber-coated ball creates a high-friction connection that absorbs shock and vibration before it reaches your device. This design is significantly more stable than plastic-on-plastic mounts, which tend to rattle or slip over time.

Yes, the modular nature of the RAM system means you can mix and match this arm with any other B-Size base, cradle, or adapter. You can easily swap out the cradle if you upgrade your device without needing to replace the entire mounting arm.

The kit includes the arm and the base, but it does not typically include the specific screws or bolts for your mounting surface. Because mounting surfaces vary from thin plastic to thick metal, you will need to source the appropriate hardware for your specific installation.
