Arkon's APVHBLOCK is an adhesive security plate that sticks to any device you want to protect with a security cable and lock (sold separately). The plate measures only 2.13" x 1.94" (small enough for most any device) and uses durable and long-lasting 3M VHB adhesive. Just remove the red, peel-away backing from the plate and stick it onto your device. Then, insert the cable lock into the lock slot on the back of the plate and lock with key. The adapter plate works with Arkon's SP-IPMCL1 as well as any Kensington-style lock for laptops, tablets, monitors, and other devices (sold separately).
