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-UN8BCU.

  • The tablet I have measures 8 3/8” x 4 7/8” - would this holder be compatible with it?

    Yes! This holder can support tablets between 2.5" - 5.75" wide and at least 7" high.

  • Which holder would I need to secure a 6" x 10" monitor for a backup camera?

    If you contact support@rammount.com with the make & model of the monitor, overall dimensions of device (H x W x D), or dimensions on any mounting hole pattern on the back, our team can take this info to confirm which of our holders or mounting plates can support this monitor.

  • Will this hold the Samsung fold 3? It is 5 wide by 6.25 tall.

    No, the holder for the Samsung Z Fold 3 is RAM-HOL-UN7BU when it's folded. If you're mounting it while it's unfolded, we'd recommend you measure your device and compare them to the dimensions listed under "Specs" on the product page, including the depth. 

  • 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.

  • Would this cradle fit an iPhone 11 as well - I need to interchange between an iPhone 11 and an 8 inch tablet.

    This holder would not be able to keep any phones secure, unfortunately. However, the ball components are modular and interchangeable; if you select any alternate holder here, you can switch this out with the tablet holder whenever you are switching devices.

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.

RAM Mounts ball size specifications and typical uses
Size Ball Diameter Max Load* Best For

C1.5" (38.1 mm)4 lbsLarge tablets, fish finders, and rougher rides
D2.25" (57.2 mm)6 lbsRugged tablets, laptops, and heavy equipment
E3.38" (85.9 mm)15 lbsLarge displays and demanding aviation or industrial use

*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.
