The RAM-B-149Z-GA41U consists of a zinc-coated U-bolt base, medium length double socket arm, and high-strength composite cradle with diamond ball base. Included in this kit is hardware that will accommodate rails from 0.5" to 1.25" in diameter. The base includes black cover caps to be placed over the exposed ends of the U-bolt. The included composite rail adapter can narrow the rail to a minimum width of 0.5". The mount is designed with a B size 1" rubber ball and socket system that has adjustment points at both ends of the double socket arm, allowing for near-infinite adjustability and ideal viewing angles.
