Thermostat Lock Box
These thermostat lock boxes are designed to fit any brand thermostat. They are available in clear plastic thermostat covers as well as metal thermostat covers. You can not see the thermostat through the metal lock boxes. All thermostat lock boxes come with 2 different mounting methods. You can either leave the existing thermostat on the wall and mount the included box frame around it or you can remove the thermostat and install the included full back behind the thermostat and then reinstall the thermostat on top of that full back. Each part number lock box is keyed alike so you may install multiple thermostat locking covers at your location and use just one key to access them all.
