Tested and approved by Dell, the Slim N17 2.0 Portable Keyed Laptop Lock for Wedge-Shaped Slots is the perfect portable lock for Dell ultra-thin and 2-in-1 laptops since it won't block valuable ports, and allows the laptop to lie flat and stable. Self-coiling carbon steel cable sheathed in plastic stretches up to six feet and shrinks down to three inches. Meets or exceeds rigorous strength testing standards. Features an omnidirectional pivoting head and rotating anchor, 5mm keying system, and free Register & Retrieve key registration and replacement. Five-year warranty. From Kensington, inventor of the laptop cable lock, and industry leader in physical device security for more than 25 years.
