The Garland G02725-16 Dial Insert Knob Overlay 150-500°F is a control-panel marking component used with compatible Garland commercial cooking equipment. The overlay displays the temperature range from 150°F to 500°F around the corresponding control knob, providing reference points for temperature adjustment. It is applicable when an existing dial insert is worn, damaged, or no longer legible. Proper selection depends on the equipment model and control configuration.
