Overview
The RAM-B-138-UN8 consists of a 2.5" diameter round base with the universal AMPS hole pattern, double socket arm and universal X-Grip®clamping cradle for 7"-8" tablets. 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 spring loaded X-Grip® cradle expands and contracts, allowing for a perfect custom fit of your 7"-8" 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.

Questions & Answers
Have a Question?
-
Does this SKU include the hardware needed to bolt it to a flat surface?
No, the hardware required to install this mount is not included. Because these are mounted to such a wide variety of materials and applications we do not know what hardware to provide. The best resource for that type of information is usually a local hardware store or the manufacturer of the vehicle you are mounting to.
-
What size screws are needed for the holes on this ball plate?
The most common screw sizes are #8, #10, M4 and M5 screws. However, if you are pairing this with any RAM® Holder, the holder will come with the necessary hardware to connect to your mount.
-

I noticed my tablet can be rotated back and forth about 15 degrees when it is in the X-Grip. Is that normal?
That type of movement is totally normal for the X-Grip. When being used for less rugged applications the small amount of movement allowed is not an issue, but sometimes when traveling at higher speeds or in bumpy environments it can be. If that is causing problems in your application, it is best to use the safety tether which will prevent that type of movement by creating tension between the phone and backplate.
