RAM Mounts Yoke Clamp Base with Ball for 15.9–31.8 mm Rails, B-Size (RAM-B-121BU)

RAM Mounts Yoke Clamp Base with Ball (RAM-B-121BU) clamps onto aircraft control yokes and other rails from 15.9 to 31.8 mm (0.625"–1.25") in diameter. The 1" rubber ball sits at a right angle to the plane of the mount, so once fitted it runs parallel to the rail – perfect for keeping a tablet, GPS or phone within easy reach in the cockpit. Combine it with a B-size double socket arm and device holder.
