Slim NanoSaver 2.0 Standard Keyed Laptop Lock features a smaller lock head with the locking cleat positioned low and the key cylinder up high and out of the way. Careful sizing and positioning of components create a premium locking solution that won't block I\/O ports and allow ultra-thin, 2-in-1 laptops with nano lock slots to lie flat and stable. Lock is strength-tested to meet or exceed rigorous standards for strength, physical endurance and mechanical resilience. 6' long, carbon steel cable resists cutting attempts. Protective sheathing helps keep attachment points such as desks and tables free from scratches. 5mm keying system is common across all of Kensington's locks to provide only one keying system to manage. Smaller key opening helps thwart picking attempts. Register and Retrieve - Kensington's online key registration program - allows quick, secure and free key replacement if lost or stolen.
