Johnson Controls GRD10A-600 Wire Guard

The Johnson Controls GRD10A-600 Wire Guard is a heavy-duty protective cage engineered to shield critical HVACR sensors and thermostats from physical damage and tampering. This rugged enclosure features 9-gauge steel wire construction with a corrosion-resistant polyester coating, making it ideal for high-traffic industrial environments or schools. Measuring 7.5 x 11.5 x 5.5 inches, it provides ample clearance for airflow to ensure accurate ambient temperature sensing without causing thermal lag. As a direct replacement for STI-9620, the GRD10A-600 includes a dedicated baseplate for secure mounting on flat surfaces. This protective wire guard is frequently utilized for thermostat protection and sensor security in commercial facilities. Its open-web design allows for easy visual inspection of the device while preventing unauthorized adjustments. This HVAC sensor guard ensures operational reliability by preventing impact-related downtime in harsh mechanical rooms.

• Enhanced Durability: Heavy-duty 9-gauge steel wire provides superior impact resistance for sensitive controls.
• Universal Compatibility: Serves as a drop-in replacement for STI-9620 models in existing security footprints.
• Included Baseplate: Simplifies installation on uneven surfaces and ensures a rigid, tamper-resistant mount.
• Optimal Airflow: The wide-grid pattern minimizes interference with sensor readings and ventilation.
• Corrosion Resistance: Polyester finish protects against moisture and chemical exposure in industrial settings.

Is the GRD10A-600 compatible with wireless thermostats?
Yes, the wire spacing is designed to allow signal transmission, though technicians should always verify signal strength after mounting the industrial control guard.

How does this model differ from the STI-9620?
The GRD10A-600 is functionally identical and serves as the OEM replacement, maintaining the same dimensions and protective specifications.

Can this be mounted over existing surface-mounted conduit?
The included baseplate and cage depth allow for flexible mounting, but check the 5.5-inch clearance against your conduit stand-offs to ensure a flush fit.
