The RAM-B-120-231U consists of a "rust-proof" stainless steel u-bolt base, double socket arm and universal side clamping holder. The side clamping holder can expand and contract, securing your device for a custom fit. Included in this package is hardware that will accommodate rails from 0.5" to 1" in diameter. The base includes black cover caps to be placed over the exposed ends of the u-bolt. The mount is designed with a RAM 1" diameter patented rubber ball and socket system that has adjustment points at both ends of the double socket arm; this allowing for almost infinite adjustment and perfect viewing angles.
