The RAM-B-400-379-M616U consists of the Tough-Claw™ rail clamp base, STANDARD length double socket arm and 1" diameter ball, containing a M6 x 30 SS HEX head bolt. The Tough-Claw™ rail clamp base is the perfect mounting base for quick and easy tool-less installation and removal on round, square, odd shaped rails and bars. 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. 

The RAM-B-400-379-M616U reduces the mounting footprint, compared to old dragonfly units that contain a large neck. This mount allows for a seamless marriage of RAM components into your Raymarine system, opening up the ball and socket system and all of our mounting options to you.
