Whether receiving hands-free phone calls, following GPS directional prompts or watching a video while safely parked, the GripTight Auto Vent Clip from JOBY allows you to securely mount and quickly position your regular sized mobile device for optimal viewing. The phone is held with the removable smartphone mount. A versatile product, your GripTight comes with an airplane clip adapter for mounting to a stowed tray table, and a 1/4″-20 stainless steel thread for use with JOBY GorillaPods and other tripods. This ability to position a mobile device on a tripod may prove useful for photographers, video crews and others while on location. With plus or minus 20-degrees of movement, selecting your preferred viewing angle with vertical or horizontal orientation is fast and easy. The TPS grip pads are designed to help avoid scratching or marring your auto vents. Made of polycarbonate-ABS plastic and stainless steel, your GripTight is both strong and durable.
