The FON-9-MB Ninja Clamp phone mount with magnetic base is a spring-loaded phone holder that accommodates most smartphones (even those with skins or ruggedized cases) up to 3.6" wide. The industrial-strength magnet is loaded with 30 pounds of pull force. Five inches of scorpion flex stays where you position it. Not only does the FON-9-MB adhere to metallic objects, it also acts as an excellent stand on any flat surface.
