These clear, tamperproof, tough polycarbonate tough covers offer an excellent way to help prevent vandalism and tampering to larger keypads, access controls, volume and lighting controls, and similar devices. Molded of clear polycarbonate (extremely difficult to break), each protected unit can be clearly seen and quickly identified. Covers increase the life and reliability of units by protecting them from accidental or intentional damage. Models available with strong piano style hinge, with the choice of open spacer or enclosed spacer, with or without a lock.
