Ask a Question
  • Is this a good choice for oddly shaped or oblong rails and handles?

    Yes, this mount is excellent for oddly shaped attachment points.

    The 1" ball attached to the RAP-B-401U can be removed exposing the 1/4 x 20 nut.

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.
