The MARS mars-70210 is a universal thermostat guard designed to protect wall-mounted thermostats from tampering, accidental damage, and unauthorized adjustment. Constructed from high-impact plastic, the guard features a clear cover and ring paired with an off-white base, allowing the thermostat display to remain visible without removing the enclosure. At 7-3/8 inches tall, 4-1/8 inches wide, and 3-1/8 inches deep, it provides ample clearance for most standard residential and light-commercial thermostat bodies. HVAC technicians and facility maintenance personnel install this guard in settings where thermostat access needs to be controlled.
This thermostat guard is suited for residential, light-commercial, and multi-unit residential applications where climate control settings must be secured against tampering. Common install locations include rental properties, hotels, schools, retail spaces, and any occupied building where unauthorized thermostat adjustment is a concern. The universal design accommodates a range of standard thermostat form factors mounted on a standard wall-plate footprint.
Designed as a universal-fit thermostat guard suitable for most standard residential and light-commercial wall thermostats within its stated interior dimensions.
Installation is typically performed by a licensed HVAC technician or qualified maintenance personnel. Power to the thermostat control circuit should be confirmed off or at low-voltage levels before handling wiring during any thermostat service performed in conjunction with guard installation. The guard mounts directly to the wall or existing thermostat sub-base using the included or standard hardware. Verify interior clearance dimensions against the installed thermostat body before mounting to ensure unrestricted access to controls where required.
