Overview

The RAM-B-121-UN8U consists of a yoke clamp base, double socket arm system and universal spring loaded X-Grip® cradle for 7"-8" tablets. The yoke clamp base will fit rails from 0.625" to a maximum of 1.25". The 1" rubber ball is positioned at a right angle to the plane of the mount; when connected to a rail, the ball sits parallel to the rail. Designed into the mount is a 1" diameter patented rubber ball and socket system with adjustment points at the both ends of the socket arm; this with a twist of the arm knob, allows you can move the mount to your optimum viewing position. The spring loaded X-Grip® cradle expands and contracts, allowing for a perfect custom fit of your 7" tablet. Included are extra easy access grip knobs, located on the back of the cradle for quick release of your tablet. The X-Grip® includes a device tether recommended for outdoor applications.

Reading part numbers

The letter after RAM tells you the ball size: RAM-B-166 uses a 1" B ball, while RAM-D-201 uses a 2.25" D ball. C size parts are the exception and carry no letter, so RAM-201U is a C size arm.
