QUESTIONS & ANSWERS

Have a Question?

Ask a Question

Can I get this cradle with a 1.5 inch C ball?

Yes, that would be RAM-HOL-UN7BCU.
What size is the "B" ball in mm?

The B size ball is 1" in diameter, which equals 25.4 mm.
I noticed my phone 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.
