The RAM-B-176-A-UN7U consists of a fork stem base, a short double arm, and a universal X-Grip mount. The included X-Grip mount features a clean and clever design with four legs that provide excellent holding power without hiding your phone behind foam pads and plastic. The spring-loaded X-Grip expands and contracts, allowing for a perfect fit for your mobile phone. The X-Grip includes a device tether, which is recommended for outdoor use. The mount is compatible with handheld devices that meet the specified dimensions. It is important to check the dimensions of your device with a case, sleeve, or film to determine the overall size. This part is designed to fit into the cylindrical bore of fork stems and works with stems measuring from 12 to 33 mm (0.5" to 1.29").
