Straight answers to the most common questions about the RAM X-Grip yoke clamp tablet mount, from rail size limits to tablet fit and viewing angle.
Quick answer
The RAM X-Grip yoke clamp mount for 9"-11" tablets fits rails from 0.625" to 1.25" in diameter and grips tablets in that size range with a spring-loaded X-Grip cradle. Measure your rail and tablet first, then plan the ball orientation before you tighten anything.
Why ball orientation changes your viewing angle
The yoke clamp base holds the 1" rubber ball at a right angle to the plane of the mount. When the clamp is closed on a rail, that ball sits parallel to the rail, so the double socket arm and cradle extend sideways from the bar rather than straight up. That geometry is useful on horizontal rails where you want the tablet offset to one side, but it limits how far you can tilt the screen toward you. Check the arm position before you commit to a rail location.
Tablet size is a range, not a guarantee
The X-Grip cradle is listed for 9"-11" tablets, but that figure refers to screen class, not physical dimensions. Tablets with thick cases, wide bezels, or unusual button placement can sit differently in the spring-loaded grips. The catalog does not list a maximum tablet thickness or case allowance, so test your actual device in the cradle before relying on it in a moving vehicle or on a boat.
RAM X-Grip yoke clamp fit questions
- Will this mount fit my rail?
- Measure the rail diameter where the clamp will sit. The yoke clamp accepts rails from 0.625" up to 1.25". If your rail is smaller or larger, this base is not the right fit, and you should look at a different RAM base rather than forcing the clamp. Measure at the exact clamping point, not the widest part of the rail.
- Does it hold a 9"-11" tablet with a case?
- The cradle is sized for 9"-11" tablets, but RAM does not publish a case thickness limit for this model. A slim case usually works, while a bulky rugged case may not seat fully. Test the tablet in the X-Grip before mounting, and remove the case if the grips do not close securely. If the grips do not spring back firmly, the case is probably too thick.
- Why does the tablet sit sideways instead of upright?
- The yoke clamp base places the 1" ball parallel to the rail when clamped, so the arm and cradle extend to the side. You can rotate the cradle in the double socket arm to change screen orientation, but the arm's starting position is offset rather than centered above the rail. Loosen the socket arm, set the screen angle, then tighten before use.
- Can I use this on a boat or vehicle?
- The yoke clamp is a mechanical clamp base, so it depends on a solid rail and a tight clamp. RAM does not list a load rating for this specific configuration in the catalog, so keep the arm short and check the clamp periodically on rough surfaces. Recheck clamp tension after the first few miles or hours of use.
Product facts
- RAM® X-Grip® Mount with Yoke Clamp Base for 9"-11" Tablets: The RAM-B-121-UN9U yoke clamp fits rails from 0.625" to a maximum of 1.25" and includes a 1" rubber ball at a right angle to the mount plane. That range covers common handrails and bars, but a rail outside it will need a different base, and the right-angle ball affects how the arm reaches the tablet.
