The STI-9100 Series Thermostat Protector with key lock helps protect thermostats and energy sensors. The cover mounts directly over the unit to prevent unwanted access, yet allows authorized use with the provided key. Molded of clear, one-eighth-inch thick, heavy-duty polycarbonate material, it’s recommended for areas vulnerable to vandalism, accidental damage or costly annoying tampering. Holes in the frame allow air to circulate freely for proper operation.
