Johnson Controls T-4002-6038 Ground Plate

The Johnson Controls T-4002-6038 is a professional-grade plaster ground plate specifically engineered for the rough-in installation of surface-mounted pneumatic thermostats in masonry and plaster wall applications. As a veteran technician knows, achieving a level, secure mount in masonry requires hardware that can withstand the rigors of construction while providing a precise foundation for the T-4000 series instrument. This mounting plate acts as a critical interface, ensuring that your pneumatic room thermostat is perfectly recessed or aligned within the wall finish for a clean, flush appearance. Designed for durability, the T-4002-6038 simplifies the transition from structural rough-in to final trim-out, preventing common alignment issues during the masonry rough-in phase. Whether you are installing a single-temperature T-4002 or a more complex dual-element controller, this plate provides the necessary structural support to maintain the integrity of the HVAC control system. Its robust construction ensures it remains stable under the pressure of plaster application, protecting the mounting points for the final thermostat assembly.

• Precise Rough-In Alignment: Specifically designed for masonry installations, ensuring T-4000 series thermostats are mounted level and secure.
• Durable Construction: Built to withstand the environmental demands of plaster and masonry work without warping or corroding.
• Standardized Compatibility: Fully compatible with Johnson Controls pneumatic mounting brackets, reducing custom field modifications.
• Professional Finish: Provides a stable ground for plastering, resulting in a cleaner final install for the end user.

• Is this plate compatible with all T-4000 series instruments? Yes, it is the standard ground plate for roughing in surface-mounted thermostats in the T-4000 product line when working with masonry or plaster.
• Does this replace the T-4002-6029 wallbox? While the wallbox is a full enclosure, the T-4002-6038 ground plate is specifically used where a plaster ground is required for a surface-mounted profile.
• How does this assist with the final trim-out? It establishes the exact depth and positioning for the mounting bracket, ensuring the thermostat cover sits flush against the finished wall.
