The RAM-B-309-412 continues on the RAM family of RAM-B-309 Clutch/Brake Motorcycle Mounts. This base consists of the same rail mount design as the RAM-B-309 Series, but WITHOUT a ball connected.

The top of this base has a 0.5" clamping socket which has been permanently connected to a 12" RAM Flex Rod. The other end of the flex arm is connected to a second RAM-B-309 Clutch/Brake Mounting Base.
