QUESTIONS & ANSWERS

Have a Question?

Ask 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.

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

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.
