The Accentra PB 4708LN (formerly the Yale 4700LN Series) is a premier Grade 1 commercial lockset specifically engineered for high-use environments. The Classroom Function (ANSI F84) is designed for maximum safety: the outside lever can be locked or unlocked by a key, while the inside lever is always active to ensure free egress at all times. Featuring a rugged cylindrical chassis and the innovative Free Wheeling lever mechanism, this lock provides superior resistance against vandalism and forced entry.
Advanced Security & Architectural Features
- Grade 1 Heavy-Duty Performance: ANSI/BHMA A156.2 Series 4000 certified, built to withstand the rigors of high-traffic school corridors and municipal buildings.
- Free Wheeling Lever Mechanism: When the outside lever is locked, it rotates freely up and down without engaging the latch. This prevents intruders from snapping the internal components by applying excessive force to the handle.
- Classroom Function (F84): Ideal for educational and utility spaces. The deadlocking latchbolt is operated by either lever unless the outside handle is locked by a key. Once locked, the key is required to release the outside lever.
- Universal Door Fit: Integrated rose support plates allow the 4708LN to adjust easily for doors ranging from 1-3/4" to 2" thick.
- Fire Rated & Accessible: UL/cUL listed for all fire doors up to 3 hours and fully compliant with ADA A117.1 Accessibility Codes for easy operation.
