QUESTIONS & ANSWERS

Have a Question?

Ask a Question
  • What are the 4 shoulder washers used for?

    The four included shoulder washers are meant to accommodate smaller screws in case the original holes on the ball plate are too large. These washers will reduce the risk of smaller screw heads stripping through the larger holes, and can be used with any of the holes on the ball plate.

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.
