The Accentra AU 4608LN Classroom Lockset (formerly Yale) is a high-intent commercial security solution specifically engineered for educational facilities, healthcare institutions, and public buildings. As part of the Series 4000 Grade 2 Standard Duty lineup, this cylindrical lockset provides the essential "Classroom Function," which allows an instructor or authorized personnel to control the exterior lever's locked status exclusively via key, preventing unauthorized locking from the inside.
Designed with the sleek and ergonomic AU (Augusta) lever, this hardware offers a professional appearance without sacrificing industrial strength. The Accentra 4608LN is the industry standard for ensuring student safety and facility security, maintaining a constant path for egress while restricting exterior access as needed.
