Ideal for thin laptops, the Slim Combination Ultra Cable Lock for Standard Slot offers our highest level of protection against cutting attempts, while allowing the laptop to lie flat and stable, and without blocking valuable ports. Extra-thick (6.5mm) six-foot carbon steel cable is sheathed in an anti-shearing plastic sleeve that resists cuts and protects surfaces. Features include a resettable four-number combination; one-handed operation; and Register & Retrieve for quick, secure, and easy combination retrieval. Meets or exceeds rigorous strength testing standards. Five-year warranty. From Kensington, inventor of the laptop cable lock, and industry leader in physical device security for more than 25 years.
