The IPM3-FSM custom fit car seat rail or floor mount fits the Apple iPad 4, 3, or 2. This mount package includes Arkon"s Custom Fit Apple iPad Holder and a seat rail floor mount with 18" flexible aluminum gooseneck. The durable plastic holder is made specifically for the iPad 4, 3, or 2, and measures just over 9.5 inches high and 7.3 inches wide. This custom holder does not fit the iPad Original, iPad Air, or iPad mini. The custom holder provides support around the edge of the iPad, and cutouts are provided for easy access to the camera, power button, and power outlet. To install the iPad, just snap the device into the holder. This holder is not compatible with protective cases. The car seat rail or floor mount is made of strong aluminum, and is ideal for those who need easy access to their iPad but prefer mounting them somewhere other than the windshield or dashboard. Use a socket wrench to install the mount to the car"s seat rail. Loosen the passenger seat track bolt, insert the included seat track bolt bracket, and then retighten the bolt. Bend the 18" gooseneck and rotate the swivel ball adapter head for 360° rotation for exact positioning of the iPad. Optional floor brackets are included for screwing the mount directly into the floor of the vehicle. (Warning: Drilling into the vehicle"s floor may damage the vehicle. Use caution and consult a mobile install professional to avoid drilling into any sensitive vehicle components.)
