The RAM® Quick-Grip™ Pro Phone Mount with Twist-Lock™ Suction Cup - Medium (RAM-B-166-PD5U) is ideal for vehicle windshields and features the next evolution of the RAM® Quick-Grip™ series. The phone holder is re-designed with a new, sleek look and integrated rubber side arms to provide a secure, no-slip hold on your phone. It also features an integrated cavity for an Apple MagSafe puck, allowing you to turn the phone holder into a wireless charging solution. Not interested in charging? No problem! The included anti-slip cover ensures a flush fit when the Apple MagSafe puck is not installed. The RAM® Quick-Grip™ Pro features a spring-loaded design that allows easy one-handed insertion and removal of your phone. The adjustable side arms ensure that your phone will remain secured in the holder without blocking any ports or buttons. This kit includes a 3.3" diameter RAM® Twist-Lock™ suction cup base that easily installs onto any non-porous surfaces. RAM® recommends installing the provided device tether when this holder is used in a vehicle with an open cockpit. It is important to verify the dimensions of your handheld device with its case, sleeve, or skin when determining the overall size.
