Robertshaw 190-067 Metal Guard

The Robertshaw 190-067 Metal Guard (also known by model number BTG-54-VLW) is a ruggedized solution for protecting critical wall thermostats from physical damage and unauthorized adjustments. Engineered for institutional and commercial environments, this thermostat lock box is constructed from a 18-gauge steel cover and a 22-gauge steel ring to withstand heavy-duty use. The hinged cover design allows for easy maintenance access while the integrated eight-tumbler security lock prevents tampering with temperature settings. To ensure sensor accuracy, the housing features ventilation ports on all four sides, maintaining the necessary airflow for consistent climate control and proper thermostat response times.

This unit utilizes a ring mounting base, which is specifically designed to allow installation directly over existing thermostats without requiring rewiring or the removal of the control from the wall. Finished in a professional beige enamel, the 190-067 provides a seamless fit for government buildings, schools, and industrial facilities. The steel thermostat guard measures 6 inches in length, 3-13/16 inches in height, and 3-1/8 inches in depth, providing ample clearance for most standard rectangular controls from major manufacturers like White-Rodgers and Honeywell.

• Institutional Durability: Heavy-duty 18/22 gauge steel construction protects against impact and vandalism.
• Simplified Installation: The ring base design eliminates the need for thermostat removal or system rewiring.
• Precision Airflow: Strategic ventilation ports maintain ambient air circulation for accurate temperature sensing.
