QUESTIONS & ANSWERS

Have a Question?

Ask a Question
  • I recently received my Ram mount (RAM-HOL-UN10B-A-379-M616U), and I found the thread length in the ball mount to be very short for my application. Do you have any similar ball mounts with longer thread length?

    Upon checking the Rap-B-379U-M616 is the only threaded stud we currently offer.

  • 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.

Size Guide

Ball sizes
  • A Size 0.56" ball
  • B Size — this product 1" ball
  • C Size 1.5" ball
  • D Size 2.25" ball
  • E Size 3.38" ball

Every RAM® mount is built around a rubber ball and socket system. The ball size sets how much weight the mount can carry. Match it to your device for smooth adjustment with a rock-solid hold.

*Approximate capacity for a standard ball with a mid-length arm. Shorter arms and steel-reinforced posts increase real-world capacity.

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.
