Appears in the issue.

Arrow Lock and Door Hardware, of New Haven, Connecticut, an ASSA ABLOY Group company, has enhanced its QL97 series classroom intruder lockset with the Key Rotation Indicator Rose. The standalone component easily retrofits to the lockset to provide a clear visual direction so the teacher knows which way to turn the key to lock the door during an emergency. The QL is a lever lock that is easy to install and can retrofit any existing door. It is available in an array of finishes and functions, in­cluding the 97 Classroom Intruder function, which allows a teacher to use a key to lock the outside lever from inside the classroom.
