The computer cover lock hinge offers maximum protection for internal computer components. The cover lock hinge adheres to the base of the computer and attaches to a FLEXGUARDŽ adhesive plate mounted on the cover of the computer. Separation of the cover lock hinge and plate is prevented by a padlock or security cable. The computer cover can not be removed until the padlock or security cable is removed. Four rubber feet are included to provide clearance on the underside of the machine. Padlock, security cable, adhesive plate, adhesive and accelerator are sold separately.
