A notebook 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. This six-foot, super-strong, steel composite cable with carbon tempered steel core helps deter theft. The patented T-bar lock simply adds more security to the tough cable. But that's not it, the lock also features a built-in defense system to guard against tampering. Even though the lock is famous for its strength, it's the sleek, stylish design that will initially catch your eye. The custom keying options allow master access, shared access or supervisor-only access. The rubber cable tie helps you keep the cable and lock organized during trips.
