Universal 3-in-1 laptop lock The new universal 3-in-1 laptop lock is a true all-rounder, allowing you to secure your laptop regardless of whether it has a standard, nano or wedge-shaped security slot. The attachments for the lock are easy to replace and are secured to a key ring, so unused attachments are always to hand. The universal 5 mm key system, patented Hidden Pin™ technology and carbon steel cable provide reliable theft protection. A rotatable and swivelling joint on the cable allows for flexible movement for easy attachment of the lock. Other features include the Register & Retrieve™ programme for fast, secure and easy replacement key service and a five-year warranty backed by Kensington, the inventor and global leader in laptop security locks. All Kensington locks are verified and tested for strength, physical resistance and mechanical resilience.
