Product Description

The RAM-B-166-UN8U consists of a 3.3″ diameter RAM Twist-Lock suction cup base, medium length double socket arm, and the popular spring-loaded RAM X-Grip 7″-8″ tablet holder. The RAM X-Grip features an ‘X’ design that expands and contracts to provide a perfect fit for your device – even if it’s in a case. Included are easy access grip knobs located on the back of the cradle for quick release of your tablet. No matter what double socket arm and mounting base you pair the RAM X-Grip with, RAM ball and socket technology allows for near-infinite adjustability to achieve the ideal viewing angle – while also extending the life of your phone by providing shock and vibration damping. The X-Grip tablet holder includes a device tether recommended for added security and peace of mind. This version of the X-Grip holder is compatible with tablets that will fit the dimensions listed. It is important to verify the dimensions of device with its case, sleeve, or skin when determining the overall size.

Proper Suction Cup Installation

Step 1: Thoroughly Clean Surface

Using glass cleaner and a microfiber cloth, thoroughly clean the desired area you wish to install the mount.

Step 2: Push Suction Cup Onto Surface

Push the suction cup base onto the surface and push against the glass while holding the twist lock to the OFF position. It is crucial you hold the base firmly and flush against the glass to ensure proper suction.

Step 3: Twist to Lock

While continuing to hold the suction base flush against the glass, use your thumb and index finger to twist the lock to the ON position. Tug on the base a little to make sure it is suctioned to the surface and not loose

Step 4: Attach Socket Arm & Holder

Attach any B size socket arm to the base and your desired device holder to complete your mount installation.
