Quad Lock is an Australian company that has developed an ingenious phone case with a unique built-in interface that pairs with a growing family of compatible mounts for the bike, the car, the office and the home. The heart of this systems approach lies in the namesake “Quad Lock” — a four-toothed interface that mechanically locks Part A to Part B. Part A in this case is a dual-density molded phone case with an integrated Quad Lock interface molded into the back. Quad Lock makes dedicated cases for all the popular phone models, as well as a 3M adhesive Universal Adapter, which makes any device compatible. Each Quad Lock Phone Case is manufactured from a durable TPU outer shell with a tough Polycarbonate core, making it a very capable phone accessory that you probably need anyway. The slim design provides complete edge-to-edge protection and no-nonsense access to all ports and buttons.Upgrade your case with the optional Quad Lock Ring/Stand, for extra security while holding your phone, and a built-in kickstand for propping the phone up on a flat surface for easy viewing.
