White Rodgers F29-0143 Clear Plastic Guard

Secure your climate control settings with the White Rodgers F29-0143 Clear Plastic Guard, a heavy-duty solution designed to prevent unauthorized tampering in commercial and residential HVAC applications. This universal thermostat guard serves as the professional-grade direct replacement for UG-2A and UG-2C models. Built from high-impact, UV-stabilized plastic, the F29-0143 features a transparent housing that ensures the display remains fully visible while restricted from manual adjustment. The unit includes both ring base and solid wall mounting plate options, allowing for versatile installation over existing controls without requiring thermostat removal. Measuring 6-3/8 inches in length, 3-1/2 inches in height, and up to 3-1/4 inches in depth, this locking thermostat cover provides ample clearance for various White Rodgers thermostat series. Complete with one key and all necessary mounting hardware, this guard is a staple for contractors looking to reduce energy waste and maintain system setpoints in public spaces, churches, and lodging facilities.

• Universal Compatibility: Engineered as a direct mechanical crossover for UG-2A and UG-2C clear guards.
• Flexible Installation: Furnished with both a ring base for easy retrofitting and a solid mounting plate for new installs.
• Tamper Proofing: Includes a dedicated lock and key to eliminate "thermostat wars" and protect HVAC system efficiency.
• Dual Mounting: Designed to be mounted in either horizontal or vertical orientations to fit specific wall space requirements.
• Visibility: Clear polycarbonate construction allows technicians or managers to monitor temperature readings without unlocking the cover.

Is the F29-0143 compatible with non-White Rodgers thermostats?
While optimized for 1C20, 1C30, and 70/80 series White Rodgers units, the interior dimensions (6-3/8" x 3-1/2") allow it to fit most standard footprint thermostats from other manufacturers. Always verify the depth of your specific model against the 3-1/4" clearance.

Can I install this without removing the thermostat from the wall?
Yes. By utilizing the included ring base, the guard can be slid over the existing thermostat and secured to the wall, provided there is enough clearance around the base of the device.

What happens if I lose the key for the lock?
The F29-0143 uses a standard White Rodgers key (Part # F145-0999). It is recommended to keep a spare key in a secure location or on the technician’s ring for maintenance access.
