Your backseat passengers stay entertained with this flexible car seat security headrest mount for tablets. The powerful metal arm is equipped with two ball socket joints for expansive angle adjustment and easy switches between portrait and landscape display orientations. The arm base clamps onto one of your headrest?s support rods, tightening or loosening with an included Allen key. This unique clamp allows your tablet to be displayed directly behind the driver or passenger seats or directly between them. The slide-grip tablet holder protects your tablet from theft with a powerful lock and key security system and allows access to all ports, buttons, and headphone jacks, for compatibility with card readers. Also included is an optional steel security cable which tethers the holder to any permanent fixture in your vehicle for additional protection.
