Essential Security & Safety Features
- Classroom Function (ANSI F84): The outside knob is locked or unlocked by key. This allows instructors to control access while ensuring the door remains a secure barrier when needed.
- Emergency Egress: The inside knob is always active, allowing for immediate, single-motion exit at all times, which is essential for life safety and emergency protocols.
- Deadlocking Latchbolt: Features a guarded deadlatch that prevents "shimming" or "loiding" attacks, providing superior security for sensitive classroom or utility spaces.
- Standard-Duty Durability: Certified to ANSI/BHMA A156.2 Series 4000 Grade 2 standards, ensuring the mechanical longevity required for commercial institutional use.
- Professional ASA Strike: Supplied with a 4-7/8" x 1-1/4" ANSI strike with a curved lip, designed for seamless fitment in standard hollow metal door frames.
- Flexible Keying Options: Compatible with 6-pin conventional cylinders or Small Format Interchangeable Cores (SFIC) for easy integration into existing master key systems.
