RAM’s Oversize Bar Mount is ideal for attaching to oversize or irregular-shaped bars.

The RAM-B-108-238U consists of a 1″ diameter rubber ball connected at a right angle to a v-shaped base.  The RAM-B-108BU accommodates rails from 1.0″ to a maximum of 2.1″ in diameter.  To mount the RAM-B-108BU base, place the saddle-shaped plate on the rail then slide the rubber sleeve onto the selected length metal strap and wrap the  clamp strap around the rail and plate.  Tighten the side screw on the metal clamping strap with a screw driver until the strap has a firm hold on the rail.
