This galvanized steel security cable is a proven theft deterrent. It's an excellent way to protect your laptop or tablet when using in a public space or need to step away at the library. To use, thread the loop end around a table leg, park bench or any anchored structure. Insert the locking mechanism into the K-slot of your tablet, device case, or laptop, and secure with the key (included). The 10-foot cut-resistant cable provides plenty of room to work wherever you need the added security.
