A laptop is both an expensive piece of equipment and a valuable source of personal information--so you don't want it to fall into the wrong hands. Patented T-bar lock attaches into the Kensington Security Slot found in 99% of laptop computers. Designed for the ultimate defense of even the thinnest laptop. The nearly impenetrable disc-style keyed locking mechanism along with an advanced cable design provides greater security. The rotating, slim lock head and pivoting cable ensure that it attaches easily without getting in the way. Super-strong carbon steel cable offers a high level of security in a 10% thinner design. Lock Type: T-Bar Disck; Body Material: Carbon Tempered Steel.
