RAM Mounts B Size uses a 1" (25.4 mm) ball-and-socket system. It is a versatile size commonly used for phones, GPS units, small tablets and other lighter devices that need secure mounting in vehicles or at workstations.
The RAM Mounts B Size system is modular. Bases, socket arms, ball adapters and device holders can be combined to create a mounting solution for the specific installation point and required device position.
The defining feature of this size series is the 25.4 mm diameter ball. When adding or replacing components, choose B Size parts to maintain compatibility throughout the mounting system.
When configuring a mount, consider device weight and dimensions, mounting method, arm length and operating environment. A longer arm provides greater positioning flexibility, while a shorter configuration may provide greater stability in demanding applications.
How to choose RAM Mounts B Size components
What ball diameter does RAM Mounts B Size use?
B Size uses a 1" or 25.4 mm ball. Arms, bases and adapters should therefore be selected for the same B Size system.
What devices is B Size suitable for?
B Size is commonly used for phones, GPS units, small tablets and other lighter electronic devices. The suitability of a particular mounting configuration also depends on device weight, arm length and operating conditions.
Can B Size components be combined with C or D Size parts?
Components from different ball-size systems are not directly interchangeable because they use different ball and socket diameters. Where different systems need to be connected, a suitable adapter designed for the required combination must be used.
Which RAM Mounts arm length should I choose?
A shorter arm normally creates a more compact and stable mount, while a longer arm provides greater positioning flexibility. The correct choice depends on the installation point, required device position and load.
