Hidden Pin technology helps resist picking, while the 2.4 m (8 ft) carbon steel cable with plastic sheath resists cutting.

Compatibility & Fit
Nano Slot, Not Kensington Slot
NanoSaver locks fit the smaller Nano security slot used on many recent thin Lenovo notebooks and other devices. They do not fit the classic rectangular Kensington Security Slot; for those devices choose a Kensington MicroSaver 2.0 lock, or the NanoSaver Twin Head Nano/MS 2.0 Cable Lock (4XE1B81919), which has one head for each slot type.
Two Nano-Slot Devices
Both heads fit the Nano slot, so pair a Nano-slot laptop with a Nano-slot dock, monitor or desktop. For a Kensington-slot second device, choose 4XE1B81920.
MasterKey Required — Sold Separately
MasterKey locks are designed for IT-managed fleets. Lenovo specifies that this lock requires the MasterKey 4Z10P40249, which is ordered separately, so one administrator key can open every lock in the deployment.
