Fortunately, progress is being made and momentum has picked up considerably to ensure classrooms now have hardware that can be locked from either side of the door. Better yet are those that come with status indicators that unmistakably show when a door is locked, such as Corbin Russwin ML2000 Series and SARGENT 8200 Series mortise locks.
These indicators have displays that are 25% larger and more prominent than the industry average, with clearer readability and more visible colors, as well as a curved design that lets those in the room see the indicator window from up to a 180-degree angle.
