Kensington releases MicroSaver Lock for Ultra-Thin notebooks
Most people are concerned about the safety and security of their electronic products, so it makes sense that has the Kensington MicroSaver DS Keyed Ultra-Thin Notebook Lock to help you that your sensitive files will be under the ceiling.
But it is super slim and not bulky like many other versions. It is still strong, but with a hard drive and locking style entered. You add only the lock to the security slot that most laptops have.
The lock is a rubber band, with the cable hidden when not in use.
