Protect your laptop and the confidential data that's on it with the Master Keyed Combination Laptop Lock. A personal 4-number code can be selected from 10,000 possible combinations. If the code ever gets lost or forgotten, a master key is available to quickly and easily open the lock. The steel lock head is tamper-resistant and features our T-Bar Locking Technology, which securely attaches to the Kensington Security Slot found on most laptops.
