To mount the RAM-B-108BU-HUM1 base, place the saddle shaped plate on the rail then wrap the metal clamp strap around the rail and 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.
