Size Guide

Ball sizes
  • A Size 0.56" ball
  • B Size — this product 1" ball
  • C Size 1.5" ball
  • D Size 2.25" ball
  • E Size 3.38" ball

Every RAM® mount is built around a rubber ball and socket system. The ball size sets how much weight the mount can carry. Match it to your device for smooth adjustment with a rock-solid hold.

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.
