The RAM Combination Strap/Handlebar/Rail Mount/Double Socket Arm/Base from RAM MOUNTS will accommodate most common roll bar sizes on UTV's, allowing for the placement of the RAM rubber ball base. With the ball base in place, you have the foundation for mounting everything from GPS devices to radios. Designed into the mount is a 1' diameter patented rubber ball and socket system with adjustment points at both ends of the double socket arm. This mount can also be attached to smaller diameter handlebars on ATVs using the included hardware.
