Robertshaw 190-065 Metal Guard

The Robertshaw 190-065 Metal Guard (BTG-54-VL) is a heavy-duty thermostat lock box designed for high-traffic commercial environments where tamper resistance is critical. Constructed from industrial-grade 18/22 gauge steel with a baked enamel finish, this rectangular guard provides a physical barrier against unauthorized temperature adjustments. This kit features a solid mounting base, ensuring the thermostat is fully enclosed. For the service tech, the design is highly practical; it includes air circulating ports on all four sides to maintain proper airflow, preventing heat stratification that can lead to inaccurate sensor readings and short-cycling of HVAC systems. The 190-065 measures 6-1/4" L x 4-3/4" W x 3" D, making it compatible with a wide range of standard low-voltage wall thermostats. The integrated eight-tumbler type lock is keyed alike, allowing a single key to manage multiple installations throughout a facility, streamlining maintenance workflows for building managers and contractors.

• Tamper-Proof Security: Robust steel thermostat guard construction prevents unauthorized access to HVAC controls in public or commercial spaces.
• Consistent Airflow: Precision-engineered ventilation ports on all four sides ensure that the temperature control remains accurate and responsive.
• Durable Finish: The beige baked enamel coating resists corrosion and physical wear in demanding industrial environments.
• Simplified Facility Management: Features a keyed alike lock system, allowing technicians to use one key for every 190-065 unit on-site.
• Universal Mounting: The rectangular metal guard facilitates horizontal or vertical orientation to accommodate various thermostat footprints.

Is this guard compatible with wireless or smart thermostats?
Compatibility depends on the device's physical footprint. The solid base 190-065 offers interior dimensions of 6-1/4" x 4-3/4" x 3". Ensure the thermostat does not exceed these dimensions and check that the metal enclosure does not interfere with localized Wi-Fi or Zigbee signal strength.

Does the metal housing affect temperature accuracy?
No, provided there is adequate clearance. The Robertshaw metal thermostat guard is designed with louvered ports specifically to ensure ambient air reaches the internal sensor, maintaining calibration and system efficiency.

Can I install this without removing the existing thermostat?
While this model (190-065) includes a solid base which typically requires mounting behind the thermostat, many technicians surface-mount the frame around existing controls. For installations where the thermostat cannot be disconnected, a ring-base model is often preferred.
