What Our Gearhead(R) Experts Are Saying: "I stuck the MAG Universal Adaptor on the back of a slim case, and now my old phone works perfectly with my Quad Lock mounts. It's super low-profile and just as secure as a dedicated case."The Quad Lock MAG Universal Adaptor turns almost any phone or case into a Quad Lock-ready device. Using strong 3M VHB adhesive, it bonds securely to flat or slightly curved surfaces, instantly adding compatibility with both Quad Lock MAG mounts and traditional twist-lock mounts. At just 5. 3mm thick, it keeps a slim profile that won't bulk up pockets or bags. Built from a durable composite, the adaptor delivers the same strong hold we expect from the Quad Lock system. The integrated MAG functionality makes mounting faster than ever-simply position the phone and let the magnets snap into place. For those who don't want to swap cases or who use devices outside the iPhone and Samsung ecosystem, this adaptor unlocks the entire Quad Lock lineup.
