TH-192 Retrostat Kit w/ Direct Acting Fahrenheit Scale

The kit fits into large format wall openings, using "goof plate" which is included, as are integral, field adjustable limit stops, a test port for fast check of output pressure without removing the cover, field replaceable thermometer, set point dials, restrictors, and filters. Standard case cover color is Desert Beige.
