The SM688 car or truck seat rail floor mount can be used with all smartphones up to 6.75” tall, including the Samsung Galaxy Note Edge, S5, S4, S3, S2, Galaxy Note 4, 3, 2, iPhone 6 Plus and iPhone 6, 5S, 5C, 5, 4S, 4, 3GS, Amazon Fire Phone, HTC One M8, Nokia Lumia 1520, 1020, 520, 521, and Motorola Moto X and Moto G. It also fits 7" and 8" midsize tablets, including the Galaxy Tab Pro 8.4, Galaxy Tab 3 7.0 and 8.0, Galaxy Note 8.0, iPad mini, and Kindle Fire HD.
This mount package includes Arkon’s Slim-Grip Ultra Universal Smartphone or Midsize Tablet Holder and a seat rail floor mount with 18” flexible aluminum gooseneck. The smartphone or tablet is held securely in place with the Slim-Grip Ultra spring-loaded holder, and can be inserted or removed from the mount with one hand.
Included with the holder are 8 support legs (4 short and 4 longer versions). The top and bottom adjustable-leg design of the holder helps keep any side buttons and ports unobstructed. For most devices, the best mount holder configuration is to attach 2 short support legs on top and the 2 long support legs on the bottom of the holder.
The car seat rail or floor mount is made of strong aluminum, and is ideal for those who need easy access to their smartphones 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 cell phone.
Optional floor brackets are included for screwing the car dock 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.)
