WELCOME TURN - This ventilation mount has a 10cm long arm and can rotate 360 degrees around the support point so you can rotate at will to get a good visual experience while driving. PREVENT SHAKING AND DROPPING - We have changed the installation method of the traditional car phone holder and adopted a hook design that can hook, rotate and tighten the air conditioner blade tightly to prevent your phone from moving and falling. Stronger: The telescopic hook is made of metal, it will be much stronger, making the phone holder stay in place. The clip hook adopts a swivel and telescopic way to make it easier to install and remove on the drain hole. PROTECTIVE: The bottom of the clip is equipped with soft silicone, which is stable and non-slip, and will not damage the slats of the car air intake. 【Wide Compatibility】The ball head of the clip has a diameter of 0.67 inches (17 mm) and is compatible with various removable mobile phone holders in the car. The clip is not limited by the shape of the drain hole and can be installed stably with the horizontal/vertical/oblique drain hole.
