Overview

The RAM® X-Grip® Phone Mount with ATV/Side By Side Rail Base (RAM-B-231-2-UN7U) comes with everything needed to mount a phone or small electronic device to rails ranging in diameter from 0.5" - 3.15". This kit consists of a steel strap clamp base, stainless steel u-bolt base, medium-length double socket arm, and universal spring-loaded RAM® X-Grip® cradle for cell phones. The spring-loaded RAM® X-Grip® phone holder allows for a perfect custom fit across phone models and small electronic devices 1.87" to 3.25" in width through expansion and contraction of the arms. The holder features four grip knobs that attach to the arms for a secure hold; also included is a rubber device tether recommended for outdoor & high vibration applications. To ensure fit within the RAM® X-Grip®, it is important to verify the dimensions of the handheld device while within its case/sleeve/skin. The patented rubber ball and socket system with adjustment points at both ends of the socket arm allows adjustment to the optimum viewing position.

*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.
