The spiral-shaped, cut-resistant carbon steel cable is easy to transport and stable, with a maximum length of up to 1.8 m and only 76 mm when coiled. A protective cover helps shield attachment points like desks and tables from scratches. The sleek design of the Nano lock head does not interfere with I/O ports and prevents the device from lifting off its surface. Each Kensington lock is crafted with precision to meet and even exceed the strict industry standards for strength, durability, and mechanical stress. The 5 mm key system is uniform across all new Kensington locks, allowing for the management of just a single key system. The smaller key opening helps thwart theft attempts. Register & Retrieve™, Kensington's online replacement key service, provides a quick, secure, and free key exchange. Backed by a five-year warranty.
