Know before you buy
B Size refers to the 1-inch diameter rubber ball used in the RAM Mounts system. This is the industry standard for most mobile phones and lightweight electronics, ensuring compatibility with a wide range of RAM arms and bases.
No, this kit includes the mounting hardware for the base itself, but it does not include the screws or bolts required to attach your specific device holder to the round plates. You will need to source the appropriate hardware based on the device cradle you are using.
Yes, it is constructed from marine-grade, powder-coated aluminum, making it highly resistant to corrosion and harsh environments. It is a popular choice for both automotive and marine applications where vibration and exposure to the elements are concerns.
This mount is rated for a maximum weight capacity of 2 pounds for standard use, or 1 pound for heavy-duty, high-vibration environments. It is best suited for smartphones, GPS units, and small tablets.
The 2.5-inch round plates feature the standard 4-hole AMPS pattern, which is the universal mounting standard for most phone cradles and GPS holders. If your cradle has a 4-hole pattern, it will almost certainly align with these plates.
The short arm minimizes the distance between the mounting surface and your device, which reduces leverage and vibration. It is the ideal choice if you have limited space or need a more rigid, low-profile setup.
