A NanoSaver® lock secures laptops and other devices with the Kensington NanoSaver slot. An additional MicroSaver® 2.0 lock secures peripherals that feature a standard-sized Kensington security slot. The cut-resistant carbon steel cable is coated to protect 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 precision-engineered to meet and even exceed the stringent industry standards for strength, durability, and mechanical load. The 5mm key system is consistent across all new Kensington locks, allowing for the management of a single key system. The smaller key opening helps thwart theft attempts.
