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.

Short, medium, and long double socket arms compared side by side. This product uses a Medium arm — Arm lengths

The double socket arm clamps over two balls — one on the base and one on your device holder. Arm length sets your reach: short arms are the most stable, while longer arms give you more freedom to position the device.
