The RAP-B-400-238U consists of the small Tough-Claw™ base, double socket arm and diamond base adapter. The RAM Tough-Claw™ is the perfect mounting base for quick and easy tool-less installation and removal on round, square, odd shaped rails and bars. The Tough-Claw™ can be clamped on rails from 0.625" - 1.5" outer diameter.

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.
