Nite Ize Steelie Mount Phone Holder keeps your phone securely gripped with its universal and adjustable bracket designed to fit most phones with or without a case, ranging from 2.24 to 3.54 inches wide (57mm to 90mm). The Mount arms adjust to hold your phone firmly, while the release button on the back allows for easy one-handed removal. When attached to your phone, the Mount bracket magnetically connects to any Steelie Mount, enabling smooth 360-degree rotation for virtually any viewing angle. It can also attach to any magnetic surface (sold separately). Please note that many Steelie products contain strong magnets which will not damage your mobile device but should be kept away from magnetically sensitive items such as credit cards, pacemakers, or computer hard drives.
