Kensington ClickSafe 2.0 Universal 3-in-1 Laptop Lock. A lock for every slot - compatible with common security slots like T-Bar, Nano, or Wedge, regardless of laptop brand or generation. The 5mm key system is the same across all the latest Kensington locks, allowing administrators to manage a locking system (such as Master Key / Single Keyed) with just one key across various locks. The unique ClickSafe® locking mechanism allows for the attachment of the lock head with one hand and a single click. The patented Hidden Pin technology provides enhanced theft protection and guards against tampering. The 1.80-meter long carbon steel cable with plastic coating offers tamper resistance and has the same cut and theft protection as thicker cables. A special swivel joint on the cable allows for flexible movement and easy locking and unlocking. Through Kensington's online key registration program, you can quickly, securely, and easily obtain replacements for lost or stolen keys. Kensington locks are tested and verified. Each lock is precisely engineered to meet or exceed strict industry standards for strength, physical, and mechanical durability. Cable diameter: 5 mm. Cable length: 1.8 m. Dimensions: 30 x 13 x 27 mm. Weight: 0.205 kg. 5-year warranty. Color: black.
