T-4000-2141 Johnson Controls Cover

Overview

The Johnson Controls T-4000-2141 is a beige plastic thermostat cover designed for horizontal-mounted T-4000 series pneumatic room thermostats and H-4100/H-5100 series humidity instruments. This protective accessory provides a clean finish to HVAC control installations while protecting internal pneumatic components from environmental factors and unauthorized tampering.

• Durable beige plastic construction ensures long-lasting performance and impact resistance
