RAM® U-Bolt Double Ball Mount with 1/4"-20 Threaded Stud - B Size Short

The RAM-B-149Z-A-237U consists of a zinc coated u-bolt base, short double socket arm and 1" (25.4 mm) diameter rubber ball, connected to a 1/4"-20 camera thread. Designed into the mount is a 1" (25.4 mm) diameter patented rubber ball and socket system with adjustment points at both ends of the socket arm; this with a twist of the arm knob, allows for infinite articulation and optimum viewing angles. The male thread matches most standard camera and camcorder female threads found on the bottom of the camera. Included in this package is hardware that will accommodate rails from 0.50" (12.7 mm) to 1.25" (31.8 mm) in diameter. Also included are black cover caps to be placed over the exposed ends of the u-bolt and a composite adapter that can narrow the rail to a minimum width of 0.5" (12.7 mm).
