What is the distance between the holes? I need something like this with 1" between the holes.

The distance between the two holes is 2". We don't have a post clamp base with 1" between holes.

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.
