The Johnson Controls T-4000-112 is a professional-grade stainless steel wall plate cover kit engineered specifically for concealed-mounted thermostats. Designed for use with the T-4000 Series pneumatic room thermostats, this kit provides a sleek, flush-mount finish for installations that do not require external push buttons or manual overrides.
