Getting It Right
When ordering a RAM mount system or additional components, it's important that you understand the part number system. To help you understand the part number format used, we are providing the following example. It is four different sizes of a basic RAM mounting system including the corresponding arm, round base with ball.

RAM-D-101 & RAM-D-202 have 2.25" balls (D size)
RAM-101 & RAM-202 have 1.5" balls (C size)
RAM-B-101 & RAM-B-202 have 1" balls (B size)
RAM-A-102 & RAM-A-238 have 9/16" balls (A size)

NOTE: The C size 1 .5" ball does not have a letter C following the RAM- prefix code, while all other sizes do require a letter.

Important: Be careful to make sure you have the letter in the proper location of the part number so you order the correct size system or component.
