Ultrabook & Mac Book Air laptops are valuable business tools & highly desirable for thieves. But they can pose a real challenge when it comes to security. The fact is some ultra-thin laptops lack a security slot making it impossible to attach a lock & secure it from theft. Fortunately theres a solution thats just as slim & sleek as the Ultrabook itself. The Kensington Security Slot Adapter securely attaches to your Ultrabook & other peripheral devices that do not already have Kensington's built-in security slot. Simply attach the adapter with the included ultra-strong, industrial-strength adhesive & youre ready to use a laptop lock to protect your investment against theft (lock sold separately). Your Ultrabook is now ultra secure.
