The Blade - a universal Macbook laptop security lo... Moreck that allows you to secure any Macbook with an ultra-strong retractable locking slot. The adhesive bracket attaches to any device with 7 inches of flat surface area and incorporates a standard cable lock slot to the tip of the retractable blade. The Blade's minimalist style essentially hides it from plain site and is designed to complement the device in use. Adding the Blade to your laptop, Macbook, ChromeBook or tablet (iPad, Galaxy Tab, Surface, Kindle.) will also improve airflow and ventilation to help maintain optimal device operating temperature. Though simple in design the Blade Universal Lock is extremely tough and durable with the ability to hold up to 150lbs of weight. Attach a key or combination cable lock to it and add extra security to all your IT hardware. } Less
