If your laptop or other device does not have a security slot, use the Kensington Security Slot Adaptor to ensure you can use the Kensington security cable. The adaptor kit will help you attach a Kensington Security Slot to your laptop, and other peripheral devices that do not already have Kensington's built-in security slot. Once you attach the security slot to your device, you will be able to use the Kensington security cable to protect your investment against theft.
