Reading part numbers

The letter after RAM tells you the ball size: RAM-B-166 uses a 1" B ball, while RAM-D-201 uses a 2.25" D ball. C size parts are the exception and carry no letter, so RAM-201U is a C size arm.

QUESTIONS & ANSWERS

Have a Question?

Ask a Question

Will my mount be just as stable as before if I use this double ball adapter to add another arm?

No, anytime you make a mount longer or add more adjustment points you will sacrifice some stability. By adding this type of extension, you are increasing the chance that you will see movement such as shaking or vibration in the mount.
