To Know It's Locked™ when moments count or to have the simple assurance that the door is secure can go a long way in contributing to peace of mind particularly for students and teachers. But lock status visual indication has far more applications than the classroom door. It is useful in health care, retail, commercial and even for specific code compliance situations. Schlage indication trims can even be applied to outdoor settings like park or service station single-use bathrooms on exterior doors.
