Install this adhesive-backed adapter on the back of a 3rd party phone case to make nearly any phone compatible with Peak Design Mobile mounts and accessories. At just 2.5mm thick and wrapped in a beautiful weatherproof nylon canvas, the Universal Adapter is low-profile, aesthetically clean, and adheres with 3M VHB for an ultra-strong, ultra-durable connection. Like the Peak Design Everyday Case, the Universal Adapter has a brilliant magnetic/mechanical lock built right into it. We call this mounting technology SlimLink™, and it's so fast and secure that it borders on magic. With this adapter on your 3rd party phone case, you can instantly connect to all Peak Design Mobile mounts and accessories. It even works with Apple MagSafe accessories, too.
