How much weight can the different ball sizes support?
1″ ball mounts = 0 to 5 pounds 1.5″ ball mounts = to 10 pounds 2.25″ ball mounts = 10 to 15 pounds If you call the folks at RAM, they will ask where the mount will be installed as this greatly influences the amount of weight that can be supported. In mobile applications which RAM is perfect for, the above weight limits are a safe guide.
