The Accentra PB 4608LN Classroom Lockset (formerly Yale) is a high-intent commercial security solution specifically engineered for schools, universities, and public buildings. As part of the Series 4000 Grade 2 Standard Duty lineup, this cylindrical lockset provides the essential "Classroom Function," which ensures that the exterior lever's locked or unlocked status is controlled exclusively by an authorized key holder.
Featuring the ergonomic and classic PB (Pacific Beach) lever style, this hardware offers a comfortable grip while maintaining the industrial strength required for high-traffic environments. The Accentra 4608LN is designed to prioritize student and occupant safety, maintaining a constant path for emergency egress while preventing unauthorized individuals from locking the door from the inside.
Essential Safety & Security Features
- Classroom Security (ANSI F84): The outside lever is locked or unlocked only by key. This prevents occupants from accidentally or intentionally locking the door from within the room.
- Life Safety Compliance: The inside lever is always active, ensuring that everyone can exit the room immediately at all times, regardless of the locked status of the exterior.
- Deadlocking Latchbolt: Equipped with a 1/2" throw deadlocking latchbolt that provides high-level resistance against "shimming" or forced entry attempts.
- Grade 2 Certified: Certified ANSI/BHMA A156.2, Series 4000, Grade 2 for reliable, long-term performance in medium-traffic commercial settings.
- Code-Approved Protection: UL-cUL listed for fire doors up to 3 hours and fully compliant with ADA A117.1 Accessibility Codes.
