The Accentra PB 4708LN Classroom Lockset (formerly Yale) is a high-intent, industrial-grade security solution designed for the rigorous demands of school campuses, healthcare facilities, and government buildings. As a flagship model in the Series 4700LN Grade 1 lineup, this cylindrical lock provides the highest level of structural durability and life-safety compliance. The Classroom Function (ANSI F84) is engineered specifically for occupant protection: the outside lever is controlled exclusively by a key, while the inside lever remains active at all times, ensuring an unobstructed path for emergency egress.
Featuring the ergonomic and timeless PB (Pacific Beach) lever design, this hardware is equipped with the advanced Free Wheeling vandal-resistant mechanism. When the lock is engaged, the exterior handle rotates freely, absorbing excessive torque and protecting the internal chassis from forced entry or mechanical failure.
Advanced Security & Architectural Performance
- Grade 1 Heavy-Duty Performance: Certified ANSI/BHMA A156.2, Series 4000, Grade 1, providing maximum resistance against wear. Tested to exceed over one million cycles, it is built for the busiest commercial corridors.
- Vandal-Resistant Free Wheeling: When the outside lever is locked, it moves independently of the latch. This "no-stress" design prevents vandals from snapping internal components by applying excessive force to the handle.
- Classroom Security (F84): The exterior is keyed for controlled access, ensuring only authorized personnel can enter. The interior lever is always active, preventing accidental lock-ins and meeting strict fire-life safety codes.
- Fire-Rated Safety: UL-cUL listed for all fire doors with a rating up to 3 hours, essential for maintaining the integrity of the building envelope.
- Deadlocking Protection: Equipped with a 1/2" throw deadlocking latchbolt to resist "shimming" and unauthorized manipulation.
- ADA & Accessibility: Fully compliant with ADA A117.1 Accessibility Codes, ensuring the Pacific Beach lever is easy to operate for all users.
