Johnson Controls GRD10A-601 Guard

Protect sensitive HVAC controls from tampering and physical impact with the Johnson Controls GRD10A-601 Guard. This heavy-duty cast aluminum thermostat guard is designed for high-traffic commercial and industrial environments where standard plastic covers fail. The unit features a solid baseplate for secure mounting to flat surfaces or standard electrical boxes, providing a professional-grade barrier for thermostats and humidistats. Its durable silver aluminum construction ensures longevity in demanding mechanical rooms, warehouses, and public buildings.

The GRD10A-601 is engineered for a precise fit with Johnson Controls T22, T26, T28, and T91 series devices, though its universal thermostat guard design and internal dimensions of 6-3/16" H x 3-5/8" W x 2-17/32" D make it compatible with a wide range of industry-standard controls. The vented design allows for optimal airflow, ensuring the protected sensor maintains accurate ambient temperature readings. This kit includes baseplate hardware and a keyed lock to prevent unauthorized setpoint adjustments and vandalism.

• Tamper-Resistant Security: Heavy-duty cast aluminum prevents unauthorized access to HVAC settings in public spaces.

No, the integrated slotted vents are strategically placed to ensure consistent airflow across the sensing element, preventing heat buildup within the enclosure.

What mounting surfaces are supported?
The included baseplate is designed for direct wall mounting or attachment to a single or double-gang outlet box, providing a stable foundation for the guard.
