Ultrabook, MacBook and Chromebook laptops are valuable business tools, and desirable for thieves, but they are frequently too thin for a standard cable lock, or lack a Kensington Security Slot. The Kensington Ultrabook Laptop Keyed Lock has an ultra-low profile, rotating head, and even a K-slot adapter for laptops without a security slot. The lock kit includes an attractive K-slot adapter that securely attaches to your Ultrabook. Simply attach it with the included ultra-strong adhesive, loop the cable around a fixed structure, lock and your Ultrabook is now secure.
