Johnson Controls T-4002-124 Mounting Bracket

The Johnson Controls T-4002-124 Mounting Bracket is a critical installation component for any HVAC technician managing T-4000 series pneumatic room thermostats. Designed specifically for surface mounting, this thermostat mounting kit provides a stable and level foundation for both the instrument and its decorative cover. The bracket features slotted mounting holes, allowing for precise plumbing and leveling on uneven wall surfaces, which is essential for maintaining the operational integrity of sensitive bimetal sensing elements. This HVAC mounting accessory is engineered to accept standard snap-in terminal connectors, facilitating a clean interface between 5/32 in. O.D. polytubing and the thermostatÆs barbed supply and output terminals. Whether you are performing a pneumatic control system repair or a new field installation, the inclusion of T4002 mounting hardware, including drywall clips, spacers, and mounting templates, ensures a professional finish. Its corrosion-resistant construction is built to withstand high-traffic commercial environments while maintaining a low-profile aesthetic for standard wall-mount applications.

• Universal Compatibility: Engineered to secure all T-4000 series instruments, including T-4002, T-4100, and T-4752 models.
• Precision Alignment: Slotted holes and included mounting templates simplify leveling on drywall, masonry, or plaster ground plates.
• Streamlined Pneumatic Connection: The opening is specifically sized to anchor snap-in terminal connectors for secure 1-pipe or 2-pipe configurations.
• Complete Hardware Kit: Ships with drywall clips and spacers to accommodate various wall depths and rough-in requirements.

Can this bracket be used for concealed installations?
This specific model is designed for surface mounting. For concealed applications in BAS environments, an aspirator wallbox or flush wallplate may be required depending on the thermostat model.

Does it support 1/4 in. tubing?
The bracket is optimized for 5/32 in. O.D. polyethylene tubing. If your rough-in uses 1/4 in. lines, you must use 5/32 in. tubing lengths as couplers to interface with the thermostat terminals provided on the bracket.

What is the purpose of the included spacers?
The spacers allow a technician to offset the bracket from the wall surface, ensuring the thermostat remains flush within the cover even if the mounting surface is irregular.
