An Ultrabook can pose a real challenge when it comes to security. The fact is most laptop locks simply won't work with an Ultrabook or Apple MacBook because the lockhead is thicker than the laptop body. As a result, typing with a lock attached becomes a wobbly chore. What's more, some ultra-thin laptops, like the Macbook Air, lack a security slot altogether, making it impossible to attach a lockhead. Fortunately there's a solution that's just as slim and sleek as the Ultrabook itself: the Kensington Ultrabook Laptop Keyed Lock. The Ultrabook Laptop Lock has an ultra-low profile and rotating head so it fits even the thinnest Ultrabook without lifting it off the desk. And the Kensington Ultrabook Laptop Keyed Lock does it all without compromising security thanks to a carbon-strengthened steel cable and nearly impenetrable disk-style keyed locking mechanism. The Kensington Ultrabook Laptop Keyed Lock is the ideal security solution for your Ultrabook - even if it lacks a built-in security slot. The lock kit includes an attractive K-slot adapter that securely attaches to your Ultrabook. Simply attach the adapter with the included ultra-strong adhesive, loop the lock around a table leg or other anchor, lock, and relax. Your Ultrabook is now ultra secure.
