About Sargent Functions 38 & 59 (Indicator Functions)

Sargent mortise lock Function 38 and Function 59 are indicator-type functions that incorporate a visual occupancy signal — typically a vacant/occupied display visible at the door face — used in restrooms, private offices, dressing rooms, and healthcare spaces. The indicator over-travel cam assembly is a critical internal component that translates the locking or thumbturn action into movement of the indicator slide. A worn or damaged cam directly impairs the indicator's ability to display correct occupancy status.
