RAM Mounts V-Shape Base

The RAM-B-108BU consists of a 1″ rubber ball connected at a right angle to a v-shaped base and accommodates bars from 1″ to 2.1″ in diameter. To mount the base, place the saddle- shaped V plate on the bar then wrap the metal clamp strap around the rail and plate. Tighten the screw knob on the metal strap with a screw driver until the strap has a firm hold on the rail.
