The Squeeze Clamp fits most standard and plus-sized phones, including a case and accessories, up to 2.3 3.6 wide, including the iPhone 12 Pro Max, iPhone 12 Mini, Samsung Galaxy, and more. The Squeeze Clamp features two levers at its base that require a simple pinch of your thumb and index finger to open the clamp and place your phone, no extra grip needed. Don't be fooled by its easy-to-squeeze nature - the Squeeze Clamp features inner continuous force springs that amplify the hold of your phone, along with grippy arms to keep it in place through every twist and turn. The Squeeze Clamp magnetically attaches onto any Steelie Mount, allowing for smooth adjustment and hands-free viewing at any angle. On top of magnetically attaching to any Steelie Mount, the Squeeze Clamp also snaps onto any magnetic surface for hands-free viewing, from the fridge to the toolbox or car.
