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 phone can rotate back and forth 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.
