Thermostat Lock Boxes, Covers & Guards

In rentals, schools, offices, and shared spaces, thermostat covers keep setpoints from getting changed and protect the device from bumps and grime. Pick a cover style that fits the job, measure your thermostat (plus any wall plate), and leave a little extra space so buttons and bezels don’t touch the guard.
