The first component of the patent-pending iPad Lock is a hard, clear plastic case you can leave on for everyday protection. And since the iPad2/3/4 has no security slot, the case has one built in. That way you can lock the security Lock to the case, and Mount the Case to the Wall or Desk. Once the case is Mounted and Locked, it will be hard to detach the case without damaging the iPad. The lock-head has the smallest diameter of any computer lock in the world, giving an overall clean look to the iPad Security Mount.
