The Quad Lock iPhone case allows you to securely mount your phone to your motorcycle with the utmost confidence and convenience. The case is compatible with Quad Lock handlebar, mirror and fork stem mounts, so it has a wide variety of applications. Attaching and detaching your phone from the mount is a easy, simply twist and lock in one motion. The patented dual-stage lock ensures your phone is secure for the ride, whether you're cruising country roads or making the long haul across rough terrain. An optional Vibration Dampener is available to add to your Quad Lock mount for additional stability and reduces over 90% of high frequency vibrations produced by motorcycles.
