All RAM systems use a 1" ball and socket system. This super strong rubber ball and socket system provides mounting flexibility and protects electronics from damage due to vibration. All components are interchangeable so you can switch attachments at either end of the clamping stalk for maximum versatility.
Perfect mounting base for quick and easy tool-less installation and removal on round, square, odd shaped rails and bars. It can be clamped on rails from 0.625" to 1.5" diameter. Ideal for mounting tablets, action cameras, smartphones, rod holders...the options are limited only by your imagination. 4.25"×1.18". Black.
