Sargent 7G37 LB Classroom Lever Lockset
Function Information:
The Sargent 7G37 LB is a professional-grade Grade 2 Cylindrical Classroom Lockset engineered for reliability in educational, commercial, and government environments. As a cornerstone of the Sargent 7-Line Series, this lockset is designed for openings where keyed security is essential to manage access while maintaining 100% life-safety compliance. Packaged with the 808 Curved Lip ANSI Strike. The LB design features the straight B-lever paired with the contemporary L-rosette, crafted from solid one-piece cast construction for a precise, high-quality feel.
Advanced Security and Institutional Durability
The Sargent 7-Line is built to outperform the baseline requirements for Grade 2 hardware, offering facility managers "heavy-duty" performance in a versatile, standard-duty footprint.
- Exceeds Industry Standards: This lockset significantly exceeds ANSI/BHMA A156.2 Grade 2 cycle requirements, ensuring years of maintenance-free operation in high-traffic hallways and classrooms.
- One-Minute Installation: Specifically engineered for maximum efficiency, the 7G37 can be installed in one minute or less, drastically reducing labor costs for large-scale facility upgrades.
- Structural Integrity: Internal thru bolts supply unmatched strength and stability without requiring additional door preparation, fitting standard modified 161 door preps.
- Vandal Resistant Options: The solid cast levers provide a formidable barrier against abuse. For high-risk areas, optional Torx® or spanner screws and the vandal-resistant trim (FW- option) are available to further harden the opening.
Classroom Function & Life Safety (ANSI F84)
The 37 Classroom Function is the standard for school security, allowing authorized personnel to secure a room from the exterior while protecting the safety of those inside.
- Keyed Exterior Control: The outside lever is locked or unlocked exclusively by a physical key. This prevents unauthorized individuals from changing the locking status from the corridor side.
- Instant Interior Egress: The inside lever is always free for immediate exit. Occupants can never be locked inside the room, ensuring full compliance with NFPA 101 Life Safety codes.
- Deadlocking Protection: Features a 1/2" throw brass latch with a deadlocking auxiliary bolt to prevent "shimming" or unauthorized manipulation when the door is closed.
- ADA Compliant B-Lever: The straight B-lever is ergonomically shaped for ease of use, meeting all Americans with Disabilities Act standards for operation without tight grasping or twisting.
